Aim The aim of the present study is to review the literature evaluating the main steps required in complete denture rehabilitation in case of edentulous jaws in the digital workflow. Methods This review was conducted using PubMed and Scopus databases. It focuses on the following clinical and laboratory steps: the impression, the registration of the centric relation, the try-in and the finalization. Results According to the reported data in literature, impression, try-in and finalization are feasible with a complete digital approach. Registration of the centric is possible only combining the digital with the traditional one. Digital impression is accurate, but shows some limitations in the peripheral areas. The printing process, because of accuracy and its cost, can be used for the try-in of the prototype. Milling machine is more accurate than 3D printing and offers a good level of retention and of satisfaction for the patient. Conclusions In relation to optical scanning, there are still some limitations because of the impossibility to perform selective pressure in the areas of the peripheral seal. Fully digital methods to register the centric are not described. More evidence based evidence on qualitative and quantitative results is required to validate digital denture protocols.

Aim To determine the clinical safety, survival and success of the immediate dental implant placement in aggressive periodontitis patients. Materials and methods In April 2019, Pubmed, Cochrane central database, Web of Science, Lilacs and hand search were searched with no restrictions for language, publication date or follow up period. All types of prospective studies reporting the prognosis of immediate implant placement were included. Outcomes were implant survival rate, complications during placement and postoperatively and marginal bone loss around implants. Results After screening of the titles, abstracts and full text of the reported studies, none of those met the pre-determined inclusion criteria. Conclusions There was no sufficient evidence regarding the survival rate of immediately placed dental implants in patients affected with aggressive periodontitis. Long term prospective double armed clinical studies are recommended.

Aim Rehabilitation of maxillary edentulous arches is a challenging task for the Dentists. Angulated implants used for implant placement which utilizes bicortical engagement of implants at the nasal cortex and pterygoid region in a flapless manner. The aim of this study was to evaluate the clinical outcome when 6 tall angulated implants were placed in a maxilla and restored with screw-retained fixed prosthesis after 3 years follow up. Methods Total of 40 patients were considered for implant placement in the maxilla, 20 patients who underwent implant placement followed by delayed loading and 20 patients who underwent the same surgical procedure followed by immediate loading. Angulated implants were supported by Finite element analysis (FEA) comparing stress distribution on cortical, cancellous and basal bone on mesial and distal side of each implant with All-on-6 concept for maxillary arch. Results Angulated implant shows 100% survival rate in implants and prosthesis, in both delayed and immediate loading protocols of maxillary rehabilitation. The FEA based on von Misses stress, shows little higher values for All-on-6 for cortical, cancellous and basal bone when compared with Angulated 6 implants design. Conclusions Angulated implants a novel concept shows a good survival rate. Due to the bicortical engagement of implant the chances of marginal bone resorption around the implant, implant and prosthesis failure is minimal.

Aim The aim of this study was to test two different of experimental cements based on two types of polymerization techniques comparing them with one already well known in the market. Materials and methods Thirty intact central incisors, extracted for periodontal reasons, were selected and endodontically treated, then were randomly divided into 3 groups of 10 samples: Group 1, light cured composite experimental material with self-etch adhesive and dual polymerization activator; Group 2, dual experimental core build-up with self-etch adhesive and dual-polymer activator; Group 3 (control group), dual cement with self-etch adhesive and dual polymerization activator. One fiber post was luted into the root canal strictly following manufacturer’s instructions. Each sample was cut in slices in order to perform the push-out bond strength test with a testing machine. To express the bond strength in MegaPascals (MPa), the breaking load recorded in Newton (N) was divided by the area of the bonded interface (A) in mm2. The area of the bond interface was calculated as the area of the surface of a truncated cone using the formula: A = π (R + r) [h2 + (Rr) 2] 1/2, where R represents the major radius of the coronal post, r represents the minor radius of the apical post and h is the thickness of the slice in millimeters. The diameters and thickness of the slice were measured individually using a digital caliper with 0.01 mm precision. After the test, each slide was observed to detect the type of failure and classified as adhesive between cement and dentin (AD); adhesive between the cement and the post (AP); fracture of the sample, cohesive inside the post and dentin (FR); cohesive in cement (CC); mixed (M). Results Group 2 recorded the highest values of adhesion strength, group 1 the lowest. There were no statistically significant differences among groups 1 and 2 and controls. The most common failure mode was the mixed one and the less frequent was the adhesive type between the post and the cement. Conclusions Within the limitations of this study, it can be concluded that the bond strength of experimental resin cements is comparable to that of a cement marketed by the same manufacturer, used here as a control and well known in the market.

Aim To investigate in vitro interaction of dental pulp stem cells (DPSCs) in bone regeneration on titanium implants. Materials and methods Dental pulp tissue collected from extracted teeth without infection was used to obtain DPSCs. The biocompatibility of titanium implant was studied by culturing the DPSCs in conditioned media obtained by incubating the titanium implants for 72 hours. Following which the interaction of DPSCs on titanium implants was checked by wrapping the DPSCs cell sheet on SLA (sandblasted large grit acid etched) treated and smooth implants. Results Cytotoxicity test revealed that the SLA treated implants were biocompatible and did not affect the proliferation rate of DPSCs. Osteogenic study with titanium implant revealed DPSCs have the capacity to undergo osteogenic differentiation in the presences of titanium implants. Conclusions This study postulates that it is possible to construct a biologically modified implant by wrapping the dental stem cell sheet around commercially available implants in order to improve the process of osseointegration as the implant- stem cell complex contains all the factors required for osseointegration.

Intraoral scanner can simplify the prosthodontic workflow with reduction of time, cost and several steps. However, clinic conditions can affect the quality of the digital impressions, especially if the tooth is prepared with subgingival vertical finish line. This report describes a technique to manage the interim crown and to obtain accurate digital impression of an abutment tooth with subgingival vertical finish line without the use of retraction techniques.

Aim Odontogenic sinusitis is a group of infections related to dental conditions. It may involve the paranasal sinuses (upper odontogenic infections, UOs) and cervical-fascial spaces. Proper diagnosis and treatment of dental complications can be challenging due to unspecific clinical presentation. Materials and methods A retrospective study of 37 patients with acute UOs treated between January 2008 and December 2018 is presented. A clear etiological and chronological relationship between the odontogenic focus and sinonasal infection was required for inclusion in the study. Results The causes of UOs were mainly dental implantation (29.8%) and tooth extraction (18.9%). In all cases, UOs were treated with transnasal endoscopic surgery, associated with transoral procedures in 24 out of 37 patients (64.9%). Empirical antibiotic therapy was used in all cases, whereas antibiogram-driven therapy was adopted secondarily in 22 out of 37 cases (59.4%). Surgical success was achieved in 97.3% of patients. Conclusions Multidisciplinary agreement of an otorhinolaryngologist and dental surgeon is a crucial step in proper diagnosis and treatment of UOs. A correct surgical approach and antibiogram-driven therapy are key elements of correct resolution of infection.

Aim It is not common to report in the literature about complications during intraoral dental implant removal and its immediate approach during implant surgery. This report describes the approach of an intraoperative accident during an explantation and its follow up. Case report In this case, an immediate implant was placed in the presence of an implant remnant left after its partial explantation due to implant fracture during the procedure. A cone-beam CT scan was taken after six months post rehabilitation and revealed bone formation surrounding the replaced implant and the remaining titanium fragment. Results There were no functional or aesthetic alterations that affected the outcome of the treatment after 2 years of follow-up. Conclusions This satisfactory result suggests that this immediate solution can be used to obtain adequate results when failed dental implants cannot be completely eliminated, which reduces the duration of the treatment and the number of surgical procedures.

Aim To test both success and survival rate of implant placed simultaneously with sinus lift in atro-phic posterior maxilla with a residual bone height of less than 5 mm. Materials and methods A computer search strategy was developed for the following electronic databases: MEDLINE/ PubMed and EMBASE. All the relevant articles were screened involving controlled clinical trials, randomized clinical trials, prospective cohort studies. Results The selection process yielded 12 studies, published between 1999 and 2016, 6 of which were prospective, 1 was a randomized controlled trial, 5 were controlled studies. Conclusions Within the limitation of this systematic review, the qualitative data analysis revealed that the survival rate of implants placed in grafted sinus ranged from 61% to 100%; on the other hand, the success rate ranged between 75.3% to 94.8%. No significant differences were detected regarding different grafting materials used. In order to understand if the one-stage pro-cedure is an effective and predictable surgical alternative in critically resorbed maxillae, larger and well designed clinical trials are needed.

All the relevant articles were screened involving controlled clinical trials, randomized clinical trials, prospective cohort studies. \u0000Results The selection process yielded 12 studies, published between 1999 and 2016, 6 of which were prospective, 1 was a randomized controlled trial, 5 were controlled studies. \u0000Conclusions Within the limitation of this systematic review, the qualitative data analysis revealed that the survival rate of implants placed in grafted sinus ranged from 61% to 100%; on the other hand, the success rate ranged between 75.3% to 94.8%. No significant differences were detected regarding different grafting materials used. In order to understand if the one-stage pro-cedure is an effective and predictable surgical alternative in critically resorbed maxillae, larger and well designed clinical trials are needed.","PeriodicalId":42724,"journal":{"name":"Journal of Osseointegration","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2019-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89363820","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
