Guided bone regeneration (GBR) standard protocols call for filling the space underneath the membrane with autogenous bone or a mixture composed of autogenous bone particles and allogeneic bone tissue or heterologous biomaterials. This work describes the case of a GBR performed to restore a vertical bone defect with simultaneous placement of a dental implant in the posterior mandible that was carried out using a high density d-PTFE membrane and corticocancellous porcine-derived bone without the addition of any autogenous bone. Bone regeneration was assessed by histological analysis of a biopsy sample collected from the grafted site nine months after the surgery. Intraoral radiographs taken at follow-up visits showed complete maintenance of the peri-implant bone levels for up to two years after prosthesis delivery. The regenerated site successfully supported functional loading of the implant. The present case report suggests that the use of a heterologous bone substitute alone to restore a vertical defect in a GBR procedure can be as effective as the standard protocol, while avoiding the drawbacks associated with a second surgical site opening.

The present post-trial follow-up investigated the influence of titanium implants with different surface treatments on clinical behavior of soft and hard peri-implant tissues. Each of the 18 included patients received at least two adjacent implants: one control implant with a dual acid-etched (DAE) surface in their apical portion and a machined coronal part, and one test implant with a DAE surface up to its coronal portion. Peri-implant bone level change (BLC), probing depth (PD), bleeding on probing (BOP) and plaque index (PI) were recorded. A total of 42 implants was inserted. The mean follow-up period was 9.3 years (range: 5–16 years) and there were six dropouts. No implant failed. Moderate crestal bone remodeling occurred during the first year after implant insertion, with lower bone loss next to test implants compared to control ones (0.80 vs. 1.39 mm; p = 0.002). This difference was also detected at the 5- (p = 0.011), 6- (p = 0.008) and 7-year follow-up appointment (p = 0.027). No statistically significant differences were found in bone resorption between implants rehabilitated with ceramic vs. composite resin veneering material. No statistically significant differences were detected between test and control implants for BOP, PI, and PD at any time point. The results of the present study suggest that DAE surfaces reduce peri-implant bone loss in the initial phase of healing compared to machined surfaces, while they do not significantly affect soft peri-implant tissue and bone maintenance in the long-term. In conclusion, the minimally rough surfaces favour peri-implant bone maintenance and their effect is greater in the first year post implant insertion.

The aim of this prospective study was to compare implant success rate and crestal bone loss around tilted and straight implants supporting immediate-loading full-arch rehabilitations. Twenty consecutive patients with edentulous jaws treated between June 2013 and July 2015 who satisfied all inclusion and exclusion criteria were included in the study. All patients were rehabilitated through a full-arch restoration supported by 4 or 6 immediately loaded implants. Clinical and radiographic examinations were scheduled every 12 months to evaluate implant success rates and crestal bone levels. Significant differences in crestal bone levels and success rates between straight and tilted implants were investigated by means of independent statistical analysis; differences were regarded as significant if P < .05. Seventy straight and 50 tilted implants were placed to rehabilitate 14 mandibles and 12 maxillae in 20 patients. After a follow-up of 12 to 36 months, survival rate was 97.1% for straight implants and 96.0% for tilted implants; while success rates were 94.3% and 94.0%, respectively. Success and survival rates were not significantly different (P > .05). Change in crestal bone level was 0.5 ± 0.4 mm for straight implants and 0.6 ± 0.4 mm for tilted implants (P > .05). Straight and tilted implants seemed to have similar behavior after immediate loading rehabilitations. After functional loading, straight and tilted implants did not differ significantly in clinical outcome.

The hypothesis was that probiotic therapy (PT) does not offer additional benefits to mechanical debridement (MD) for treatment of diabetic subjects with peri-implant mucositis (PM). This study compared the influence of PT as an adjunct to MD for the treatment of PM in type2 diabetic and non-diabetic patients over a 12-month follow-up period. Patients with and without type-2 diabetes were encompassed. Based upon treatment-procedure, PM patients were categorized into 2 groups: (a) Non-surgical + PT; and (b) Group-2: Non-surgical MD alone. Demographics and education statuses were recorded. Gingival (GI) and plaque (PI) indices, crestal bone loss (CBL) and probing depth (PD were measured at baseline and after 6- and 12-months. Significant differences were detected with P<0.01. The HbA1c was significantly higher in diabetic patients at all time durations than patients without type-2 diabetes (P<0.001). Baseline GI, PI, PD and CBL) were comparable in all groups. In patients with type-2-diabetes, there was no difference in PI, GI, PD and CBL at 6- and 12-months’ follow-up. In patients without type-2 diabetes, there was a significant reduction in PI (P<0.01), GI (P<0.01), and PD (P<0.01) at 6-months and 1-year follow-up than their values at baseline. In patients without type-2 diabetes, MD with or without adjunct PT reduces soft tissue inflammatory parameters in patients with PM.

Aim: This in vitro study aimed to evaluate the effects of implant designs on primary stability in different bone densities and bony defects. Methods: Five implant types (tapered-tissue-level, tissue-level, zirconia-tissue-level, bone-level, and BLX implants) were used in this assessment. The implants were inserted into four different artificial bone blocks representing varying bone-density groups: D1, D2, D3, and D4. Aside from the control group, three different types of defects were prepared. Using resonance frequency analysis and torque-in and -out values, the primary stability of each implant was evaluated. Results: With an increased defect size, all implant types presented reduced implant stability values measured by the implant stability quotient (ISQ) values. Loss of stability was the most pronounced around circular defects. Zirconia and bone-level implants showed the highest ISQ values, whereas tissue level titanium implants presented the lowest stability parameters. The implant insertion without any thread cut led to a small improvement in primary implant stability in all bone densities. Conclusions: Compared with implants with no peri-implant defects, the three-wall and one-wall defect usually did not provide significant loss of primary stability. A significant loss of stability should be expected when inserting implants into circular defects. Implants with a more aggressive thread distance could increase primary stability.

ABSTRACT Background The use of endosseous dental implants has led to more sophisticated fixed options when considering treatment of patients with distal extensions. The use of narrow-diameter implants may reduce the necessity for bone augmentation. The mechanical strength of titanium is limited, so titanium alloys with greater tensile and fatigue strength may be preferable. Purpose The purpose of this study was to evaluate clinically and radiographically the performance of narrow-diameter bone level implants made from titanium-zirconium alloy (TiZr, RoxolidTM) in restoring unilateral atrophic mandibular distal extensions with fixed dental prostheses. Materials and methods Twenty partially edentulous patients with unilateral atrophic mandibular distal extensions received two 3.3 mm diameter bone level TiZr implants (Straumann AG, Basel, Switzerland). The two implants were restored with 3-units ceramo-metal fixed partial dentures. Standardized clinical and radiographic parameters (survival rate, probing pocket depth and marginal bone loss) were evaluated at the time of the completion of the prosthetic treatment (baseline) and after 3, 6 and 12 months of functional loading. Prosthetic complications were also assessed. Results The survival rate for narrow-diameter bone level TiZr implants was 100% after 1 year of functional loading. There were no statistically significant differences between the values of probing pocket depth over the follow-up period. All implants showed less than 1 mm of marginal bone loss at the end of the follow-up period. Conclusion Within the limitations of this 1-year pilot study, the use of narrow-diameter bone level TiZr implants appears to be predictable in restoring the unilateral atrophic mandibular distal extensions. This type of implants meets established success and survival criteria after 1 year. How to cite this article El-Sheikh AM, Shihabuddin OF.

The interrelationship between pulpal and periodontal disease primarily occurs through the intimate anatomic and vascular connections between the pulp and the periodontium. The purpose of this case report is to present the treatment of two cases of mandibular first molars displaying endodontic-periodontal lesions with and without the use of regenerative bone techniques. The endodontic treatments were performed under an operating microscope in two appointments. Later, periodontal therapy was performed with a non-surgical approach in one case and with guided bone regeneration in the other. A 12-month radiographic and clinical follow-up showed periapical and periodontal healing in both cases. The present case report demonstrates that an interdisciplinary approach can help improve the prognosis and maintain natural dentition. Moreover, periodontal regenerative therapy can be performed to guide the wound healing towards the regeneration of lost periodontal structures.

Objective: To determine the evidence on the adverse effects of placing dental implants in healthy growing children. Study design: A systematic search was conducted in five electronic databases: PubMed, Ovid, Cochrane, EBSCO host, ProQuest. Studies on implants placed in children below the age of 19 years, with loss of tooth either due to trauma or caries were included, whereas, studies on mini implants and implants placed due to congenital absence of teeth were excluded. The articles that fulfilled the inclusion criteria were analyzed based on the predetermined criteria of success. Results: A total of 8 publications fulfilled the inclusion criteria. All the included articles were case reports/series, involving a total of 16 implants (15 maxillary, one mandibular) in 11 adolescents (7 boys and 4 girls). The age of implant placement ranged between ten to 17 years with a mean age of 13.4 years and the follow up period, 4.5 months to 13 years. Pain, paresthesia, mobility or peri-implant radiolucency was not reported in any case report, indicating good integration. Radiographic crestal bone loss, probing depth and implant esthetics were not mentioned. The infraocclusion was not reported in 5 cases (age: 11–17 years, follow up: 4.5 months-two years), however, it was an adverse effect in 6 cases (age: ten-17 years, follow up: three-13 years). Conclusion: There is insufficient evidence to contradict the placement of dental implants in healthy growing children; the only reported adverse event is infraocclusion, the management of which too is discussed. However, as all the data is from case reports, the result should be interpreted with caution. Therefore, well-designed randomized controlled trials are needed to address this gap in the literature.
