Objectives: Implant placement in atrophic ridges with severe horizontal bone deficiency without adequate bony housing around the defects remains a significant clinical challenge. The aim of this case series is to evaluate the effectiveness of alveolar ridge splitting (ARS) with simultaneous implant placement. Materials and Methods: Four patients with severe horizontal bone deficiency in atrophic ridges received ARS with simultaneous implant placement. The stability of the widened ridges was evaluated by superimposition of initial and postoperative CBCT images. The ridge thickness at baseline (RT0) and at least 6-month postoperation (RT1), as well as horizontal bone gain (HBG), were measured with the reference of implant platform. Results: All 7 implant sites healed uneventfully without complications. The mean RT0 was 3.84 ± 0.56 mm at baseline; the mean RT1 was 7.61 ± 0.96 mm at least 6-month postoperatively, with the mean HBG of 3.77 ± 0.80 mm. The results demonstrated significant HBG and sufficient bone thickness around implants after ARS with simultaneous implant placement in all cases. Conclusion: The ARS technique with simultaneous implant placement is an effective and predictable treatment modality to augment ridge width significantly for narrow atrophic ridges without adequate bony housing.

Abstract: Endodontic-Periodontal Lesions (EPL) often progress slowly without obvious symptoms, unless exacerbated by swelling or pus discharge. The aim of this report is to investigate whether a short waiting time (simultaneous or within a 1-month interval) between non-surgical endodontic and periodontal treatment affects the prognosis, root resection considerations and influencing factors associated with the efficacy of treatment for true-combined EPL. Materials and Methods: This case series selected three examples of true-combined EPL. In cases 1 and 2, a short waiting period between non-surgical endodontic and the subsequent periodontal treatment was implemented, simultaneously in case 1 and after a 1-month interval in case 2. In case 3, we presented a treatment sequence of vertical root fracture related EPL. Probing depth (PD), clinical attachment level (CAL), furcation involvement, mobility and radiograph were recorded and evaluated 6 months after the final treatments. Results: In case 1, the deepest PD changed from 8 mm to 4 mm; CAL changed from 11 mm to 8 mm. In case 2, the deepest PD changed from 10 mm to 3 mm; CAL changed from 10 mm to 5 mm. In case 3, the deepest PD changed from 7mm to 3mm; CAL changed from 10mm to 4mm. As for the radiograph, all cases with obvious bone fill 6 months after the final treatments. Conclusion: When facing the true combined EPL, from these cases we can implement non-surgical endodontic and periodontal treatment simultaneously or within a short waiting period, with a favorable outcome coming after a 6 month follow up. When the vertical root fracture is suspected, inflammation control and a flap operation to ascertain the diagnosis are indicated.

Abstract: Objective: This study was aimed at systematically reviewing the literature on the microbial profiles of peri-implantitis (PI) as analyzed using 16S rRNA gene sequencing methods. Methods: An electronic search of PubMed, Scopus, Embase, and Cochrane databases was conducted to find clinical trials published up to November 2021. The inclusion criteria were studies assessing the microbiome of PI by using 16S rRNA gene sequencing analysis in otherwise healthy patients. Results: Of 70 potentially eligible articles, data from 12 studies on 636 samples from peri-implant sites and natural tooth sites were included in this study. In 10 out of 12 studies the PI microbiome showed distinct microbial profiles from healthy implants (HI) or periodontitis teeth (PT) or healthy teeth (HT), whereas 2 studies only discussed the difference in smoking and disease severity in PI. The main observed genera were Actinomyces, Campylobacter, Fusobacterium, Mogibacterium, Moraxella, Prevotella, Treponema, and Porphyromonas. Five studies showed higher microbial diversity in PI than HI, whereas 4 studies showed lower microbial diversity in PI than HI, and 2 studies showed similar microbial diversity to HI and PT. One study suggested that microbial diversity in smokers was lower than in non-smokers and one study suggested that disease severity in PI reduced the diversity of the microbiome. Four studies revealed a significant correlation between microbiome composition and clinical parameters, particularly the probing depth. Conclusion: This systematic review revealed that increases in peri-implant probing depth are associated with substantial changes in the submucosal microbiome and increasing levels of dysbiosis. The microbial profiles of PI seem distinct in HI, PT, and HT. However, the results for PI-related species and microbial diversity were inconsistent because of the heterogeneity of the study designs.

Abstract: Short-term outcome of dental implants is predictable, but variable long-term results are noticed. Cluster effect of implant failure had been reported in previous studies and many patient-related risk factors have been claimed to be associated with implant failure. This review was investigated the correlation between patient-related factors and late implant failure, and further provide a preview of potential risk indicators in late implant failure for clinicians. Regarding to current evidences, history of periodontitis does have negative effects on implant survival, but comparable results can still be obtained after intensive periodontal treatment and maintenance. The direct cause-and-effect of smoking habit and late implant failure can still not be determined. Well-controlled Diabetes mellitus (DM) patients present comparable long-term outcomes. Moreover, some moderate-controlled DM (HbA1c = 7.2 – 10.0%) patients can still benefit from implant therapy under limited risk. Most of the studies suggest that implants in bruxers may have higher chance of mechanical complication. The negative effects of radiotherapy (RT) are related to its dose, interval between implantation and damage of salivary gland. Incorporating oral rehabilitation plan before RT may provide better outcomes. Lastly, poor compliance to supportive implant treatment (SIT) is significantly related to peri-implant bone loss, increasing probing depths and eventually implant failure. Before implant therapy, we should pay more attention about patient’s condition and further make comprehensive treatment plan for long-term success. Check DM patient’s blood sugar and consult physical doctor before surgery. Incorporate oral rehabilitation plan before RT to cancer patient and communicate with cancer physician. Suggest patient quit smoking and consult specialist for management bruxism condition. Lastly, keeping SIT program is important in implant patients, especially with history of periodontitis.

Abstract: Objectives: Narrow-diameter implants (NDIs) may serve as a feasible treatment alternative for the rehabilitation of specific cases. The aim of this review article was to assess the clinical outcomes of restoring stress-bearing posterior edentulous ridges with NDIs. Materials and Methods: An electronic search was conducted in MEDLINE/PubMed and Cochrane Library databases and enriched by hand search. Prospective and retrospective clinical studies, from January 2000 to November 2021, with at least 10 patients and a follow-up period of at least 1-year after functional loading, were included. Marginal bone level (MBL) and implant survival/success rate were set as primary outcome variables. Results: From the initially identified 2,401 articles, 17 clinical studies fulfilled the inclusion criteria and were included. Of the selected studies, mean MBL after loading was within 2 mm at different time intervals up to 10 years. Recorded implant survival rate was 92.6-100%, 95.3-100%, 95.3-100%, and 95.1-97.9% after 1-, 3-, 5-, and 10-year, respectively, while success rate was 92.6-100%, 95-100%, and 95% at 1, 3, and 10 years. Biological and prosthetic complications were observed. Conclusions: Within the limitation of the present study, it could be concluded that the use of NDIs for rehabilitation of posterior jaws is a viable treatment alternative, with comparable MBL and implant survival/success rate to standard-diameter implants (SDIs).

Abstract: Background: Insufficient width of keratinized tissue (KT) around dental implants is a potential contributing factor of peri-implant diseases, and soft tissue grafting procedures are recommended for long-term maintenance of dental implants. A bulk free keratinized mucosal graft (FKMG) from the hard palate in conjunction with an apically positioned flap (APF) is the gold standard for KT augmentation. However, the major shortcomings are limited sources of the grafts and risks of donor wound morbidity. This case series proposed an alternative approach for KT augmentation by the combination of advanced platelet-rich fibrin (A-PRF) with a strip FKMG. Material and methods: Two patients with insufficient peri-implant KT width (< 2mm) bilaterally were enrolled for the split-mouth observation. Two different surgical methods were utilized to augment KT in the same patient. The recipient bed was fully covered by a bulk FKMG on one side, and topical hemostatic agents were applied to the donor wound. A strip FKMG was placed at the apical border on the other side with the remaining recipient bed being covered by an A-PRF membrane, and the donor wound was protected by another A-PRF membrane. Results: All four treated sites exhibited 4-5 mm significant gain in KT width, and the width was maintained for 12 months. Compared with the surgeries using a bulk FKMG, patients reported lower postoperative pain scores with a strip FKMG and A-PRF combination. Conclusion: The combination of an A-PRF membrane and a FKMG strip demonstrated satisfactory short-term outcomes for peri-implant KT augmentation, and donor wound morbidity was reduced.

Abstract: After tooth extraction, the alveolar ridge undergoes resorption and atrophy, which usually leads to a wide range of tissue dimensional changes. Preservation of the alveolar ridge can maintain its volume, reduce ridge resorption, and help subsequent dental implant treatment. This retrospective cohort study aims to investigate the marginal bone stability of implants placed in alveolar ridge preservation areas using deproteinized bovine bone mineral with 10% collagen (DBBM-collagen) combined with a native collagen membrane (CM). In this study, forty-seven implant sites divided into either intact or defective extraction sockets were included, using vertical bite-wing films to measure the bone level at baseline, 6 months, and 12 months after implant prosthesis placement. The result of peri-implant mean bone loss was -0.03 ± 0.84mm at 12 months compared to baseline. There was no significant difference in mesial and distal sites compared to baseline. In addition, no significant difference was found between the defective and intact sockets for marginal bone changes. Therefore, ridge preservation combined with DBBM-collagen and CM can provide an ideal alveolar ridge, simplify dental implant procedures, and maintain implant marginal bone stability.

Preservation of the alveolar ridge can maintain its volume, reduce ridge resorption, and help subsequent dental implant treatment. This retrospective cohort study aims to investigate the marginal bone stability of implants placed in alveolar ridge preservation areas using deproteinized bovine bone mineral with 10% collagen (DBBM-collagen) combined with a native collagen membrane (CM). In this study, forty-seven implant sites divided into either intact or defective extraction sockets were included, using vertical bite-wing films to measure the bone level at baseline, 6 months, and 12 months after implant prosthesis placement. The result of peri-implant mean bone loss was -0.03 ± 0.84mm at 12 months compared to baseline. There was no significant difference in mesial and distal sites compared to baseline. In addition, no significant difference was found between the defective and intact sockets for marginal bone changes.

Abstract: Regenerative surgery is an effective treatment of intraosseous defects, however, subject with thin gingival tissue phenotype and bone dehiscence defect tends to have more post-surgery gingival recession. The gingival recession is considered as soft tissue loss, which may affect the result of periodontal regeneration. Therefore, this case series aimed to describe a periodontal regenerative surgery combined with subepithelial connective tissue graft (SCTG) in intraosseous defects associated with buccal gingival recession would make periodontal regeneration more predictable. Materials and Methods: The case series describes a surgical approach to improve regenerative parameters in deep intraosseous defects associated with buccal gingival recession. Teeth with buccal bone dehiscence or furcation involvement were included. The surgical technique consisted of an SCTG placed on the buccal dehiscence defect or furcation area to thicken the soft tissue wall, then treated with enamel matrix derivative and biomaterials as regenerative scaffolds inside the intraosseous component of the defect. Results: In all cases, there were buccal gingival margin thickness increased, significant clinical attachment level gain, bone level gain, reduced probing pocket depth, and partial root coverage at least one year after the surgery. The radiographs demonstrated increased bone density of the deep intraosseous defects associated with buccal gingival recession in both single root and furcation-involved teeth. Conclusion: The combination of regenerative treatment and SCTG in intraosseous defects associated with buccal gingival recession in a single root or furcation-involved molar supports the stability of the gingival profile and improves root coverage outcome as well as periodontal regeneration.

Abstract: Objectives: Various dynamic navigation systems have been developed to enhance the accuracy of implant positioning and prevent damage to anatomical structures such as the inferior alveolar nerve and maxillary sinus during osteotomies. This case report aims to demonstrate a surgical method that combines a dynamic navigation system with crestal sinus lifting and simultaneous implant placement in the maxillary molar region. Materials and Methods: Two systemically healthy patients with extraction and socket preservation of a hopeless maxillary second molar were included in the study. Preoperative cone-beam computed tomography (CBCT) revealed limited residual bone height for implant placement after the healing period. Virtual planning of the implant was conducted using dynamic navigation planning software. Both patients underwent crestal sinus lifting through hydraulic pressure and simultaneous single implant placement assisted by the dynamic navigation system. Postoperative CBCT was performed 6 to 7 months after the implant placement to evaluate the implant position and increase in bone height. The postoperative implant position and orientation were compared to the preoperative virtual plan. Results: In both cases, the surgeries were uneventful and no postoperative complications occurred. Postoperative evaluation revealed that the global platform deviation was 1.60 and 2.24 mm, the global apex deviation was 1.46 and 2.13 mm, and angular deviation was 1.18° and 5.50° in case 1 and case 2, respectively. Conclusion: Combined dynamic navigation system with crestal sinus lifting by hydraulic pressure and simultaneous implant placement is a safe, accurate, and reduced morbidity surgical protocol in the maxillary molar region.
