Aim In the dental literature there are a number of studies about digital impressions. They mainly are focused on the reproducibility of the measurements or on the validity, accuracy, trueness and precision of the scans compared with conventional materials, or on the reaction of patients to these new methods. The purpose of this study was to systematically review existing clinical trials reporting about intra oral scanning procedures on sound teeth. Materials and methods PubMed, Cochrane Library and Web of Science databases were electronically searched and enriched by hand searches. The query terms “randomized clinical trials”, “in vivo study”, “sound teeth”, “intraoral scanner”, “digital dentistry” combined with the Boolean operators “OR” and “AND” have been used. No language or time limitation was applied. Selection criteria: oly randomized in vivo studies where sound teeth had been scanned intraorally were considered. Results Twenty-four out of more than three hundred studies were selected for the review. Conclusion In literature there are enough randomized clinical trials about sound teeth. They report about many clinical aspects.

Aim The aim of this prospective clinical trial was to analyze, using the Functional Implant Prosthodontic Score (FIPS), the clinical resultsof three different abutment-implant connections (1 hexagon vs 2 conical types) single-unit restorations after one year of clinical service. Material and methods Thirty patients were restored with cement-retained crowns on soft tissue level implants (10 TTc Windmix, 10 TTk Windmix and 10 Aadva GC) in posterior sites and followed-up for 1 year. FIPS was applied for objective outcome assessment beside clinical and radiographic examinations. Five variables were defined for evaluation, resulting in a maximum score of 10 per implant restoration. The patients’ level of satisfaction was recorded and correlated with FIPS. Results All implants and connected crowns revealed survival rates of 100% without any biological or technical complications after three years of loading. The total FIPS recorded for group 1 was 44, 43 in group 2 and 42 in group 3. The mean total FIPS score was 8.6±1.1, ranging from 6 to 10. The variable “bone” revealed the highest scores (2.0; range: 2–2), as well “occlusion” (2.0; range: 2–2). Mean scores for “design” (1.7 ±0.4; range: 1–2), “mucosa” (1.6±0.5; range: 1–2), and “interproximal” (1.5±0.6; range: 1–2) were more challenging to satisfy. The patients expressed a high level of functional satisfaction (80.5±2.5; range: 65–100). No type of connection showed to be superior to the other two. No statistically significant differences were found among the three tested groups. A significant correlation was found between FIPS and the subjective patients’ perception with a coefficient of 0.80 (P < 0.0001). Conclusions The findings of the clinical trial indicated the great potential of both conical and hexagon connections and their good performance after 1 year of clinical service. FIPS showed to be an objective and reliable instrument to assess implant success.

Aim Extraction of the teeth and a healing period of 4-6 months followed by implant placement is a common procedure for the treatment of teeth with bad prognosis. This study was done to assess radiographically the quantity and quality of bone formed in the region of mandibular first molar after extraction of the tooth and immediate implant placement with Concentrated Growth Factor (CGF) grafting. Materials and methods A total of 10 subjects were selected for this prospective study. Extraction of mandibular first molars was carried out and implants were immediately placed with CGF grafting. A Cone Beam Computed Tomography (CBCT) was taken immediately after implant placement and after six months of undisturbed healing, radiographic evaluation was carried out using CBCT to assess the quantity and quality of new bone formed around implants. The collected data were statistically analyzed. Results CBCT results showed a mean bone gain of 2.3 mm in buccal, 1.52 mm in lingual, 2.97 mm in mesial and 4.26 mm in distal aspect respectively. No statistically significant change was noticed in bone density comparing the first two and last two threads of implants inserted with concomitant placement of CGF into the extraction socket. Conclusion This study indicates the possibility to perform immediate implant placement in fresh extraction sockets with the use of CGF as an alternative to conventional grafting. Further research needs to be carried out on the subject to validate the results obtained in this study.

Aim A case is reported of the rehabilitation of a completely edentulous patient suffering from gagging problems and with low financial resources with conventional complete dentures. Case report A 55 years old patient came to the outpatient clinic of the prosthodontics department, Faculty of Oral and Dental Medicine, Cairo University seeking for complete denture prosthesis to restore function and esthetics. He reported problems with his complete dentures as he had an exaggerated gagging reflex which interfered with upper denture wearing. Besides, his mandibular denture was unstable and poorly fitted. This patient was strongly recommended for implant prosthesis and, because of his low financial conditions, an implant overdenture was the most proper treatment. Four implants were placed in the upper arch with self-aligning attachment and two implants in the lower arch with self-aligning attachments. Conclusion Implant overdenture is a simple, easy, comfortable, effective solution for restoring edentulous patients at a low cost and with no need for bone augmentation procedures.

Aim According to recent literature, the accuracy of digital impression can be compared with traditional impressions for most indications. However, little is known about their suitability in digitizing edentulous jaws in view of mobile prosthetic rehabilitation. The aim of this study was to compare in vivo an intra-oral scanner with conventional impression in case of maxillary edentulous jaws. Material and methods Four (1 male, 3 female) subjects who had no previous experience with either conventional or digital impression participated in this study. Digital impression were taken using an intra-oral scanner. After that conventional impressions of maxillary edentulous jaws were taken with an irreversible hydrocolloid impression material. Then all IOSs datasets were loaded in a three-dimensional evaluation software (3DReshaper 2017, Hexagon), where they were superimposed on the model obtained using conventional impression and compared. Results The mean value of difference between the two impression techniques ranged from 219 to 347 μm. The comparison of models obtained with the two techniques showed that the compression given by the impression material on the peripheral areas, such as oral vestibule and soft palate, determined the most important differences recorded. Conclusion Digitizing edentulous jaws with the use of IOS appeared to be feasible in vivo, although peripheral tissue were not effectively reproduced. On the basis of the results of this study, the authors could not recommend the use of IOS for digitization of edentulous jaws in vivo in view of mobile prosthetic rehabilitation, until it will be found a way to give a selective pressure in peripheral areas as occurs during edging of impression tray.

Aim This in vivo study aims to compare the quantity and quality of bone formation around dental implants inserted following Tatum’s approach with placement of Concentrated Growth Factors (CGF). Materials and methods This prospective study involved 20 patients requiring maxillary sinus augmentation for missing maxillary first molars. These patients were randomly divided into two groups: one in which sinus augmentation was followed by placement of CGF and simultaneous implant placement and the other in which no grafting material was used also followed by immediate implant placement. Radiographic assessment was carried out six months postoperatively using Cone Beam Computed Tomography (CBCT) to assess the quantity and quality of the new bone formed. Results CBCT analysis showed a mean bone gain of 3.193 mm in subjects in the test group and 4.47 mm in the control group. Also, a statistically significant difference was noted in bone quality in the test group when compared to controls. Conclusion This study indicates that direct sinus augmentation with CGF and immediate implant placement is a viable treatment option for the atrophic posterior maxilla. However, further studies are required to validate the quantity of bone formation preferably using Computed Tomography (CT).

Aim Success of dental implants depends mainly on osseointegration between bone and titanium surface. Since osseointegration relies on balanced bone turnover, it can be assumed that any conditions that interfere with homeostasis of bone modelling/remodeling might be detrimental to survival of dental implants. Obesity has become a serious public health problem, and has been shown to be closely linked to a wide array of pathophysiologic consequences, including insulin resistance or pre-diabetes. Obese-insulin resistance or pre-diabetic condition is characterized by hyperinsulinemia with euglycemia. The impacts of type 2 diabetes mellitus (T2DM) on the success of dental implants and the factors to improve osseointegration in diabetic condition have been thoroughly investigated. Much evidence demonstrated that T2DM impaired the bone healing around dental implants, possibly due to hyperglycemic condition. However, the effect of obese-insulin resistant condition or pre-diabetes on survival of dental implants has not been investigated. This review aims to summarize the current findings of effect of obesity toward bone health and osseointegration of dental implants.Conclusion The studies favor the relatively negative impact of diabetes on osseointegration, but more scientific studies are necessary.

Aim Purpose of this RCT was to evaluate the denture retention and success rate of totally edentulous patients in single median versus two inter-foraminal implant-supported mandibular over-dentures on.Material and methods Twenty-four totally edentulous patients were selected in this trial. The eligible patients were allocated randomly into two equivalent groups of 12 participants each. A single-implant (G I) or two inter-foraminal implants (GII) were located in the mandible. Three months later, pick up of the locator attachment wa performed to all implants and denture bases. Assessments of denture retention and success rate of implants were measured at the three, six, and twelve month's follow-up assessments. The study consists of twenty-four totally edentulous patients (14 males and 9 females) with age range of 59.6 years. Thirty six implants were inserted (12 in single-implant and 24 in the two inter-foraminal implants). All patients accomplished the twelve months period of follow-up.Results Regarding denture retention, the two inter-foraminal implant group (GII) showed statistically significant differences compared to the single-implant group (GI). Concerning success criteria of implants the results revealed insignificant differences between patients in both groups.Conclusion Single-implant mandibular over-dentures may be recommended as an alternate treatment option for the management of edentulous patients in populations with low economic status.
