- To test the null hypothesis of no difference in the implant failure rates, postoperative infection, and marginal bone loss after the insertion of dental implants in bruxers compared with the insertion in non-bruxers against the alternative hypothesis of a difference.

- Purpose: The aim of the review was to compare the long-term clinical success of minimally and moderately rough dental implants in terms of differences in marginal bone loss and survival. Materials and Methods: The pertinent literature was searched by using the PubMed database and requesting major manufacturers to provide reports of their commercially available dental implant systems. Clinical reports meeting the following criteria were reviewed: results of at least 5 years of follow-up, availability of baseline and follow-up radiographs including intraoral radiographs, and availability of marginal bone loss measurements from the baseline to the end of the follow-up period (5 years or more). All the recorded data were analyzed statistically. Results: Seventy-one of 1202 articles met the inclusion criteria. Maxillary moderately rough implants were found to have significantly higher long-term survival rates than maxillary minimally rough implants; no such difference was noticed in the mandible. Significant marginal bone loss occurred around all the implants in the first year but stabilized thereafter, indicating the absence of progressive bone loss. Conclusion: The dental implant systems commercially available today have good long-term clinical success in terms of survival and marginal bone loss.

- Purpose: To investigate the bone regenerative effect of polymer and collagen incorporation to synthetic bone graft materials. Materials and Methods: The bone ingrowth of biphasic graft materials was tested in a rabbit calvaria defect model after chemical characterization: HA/TCP (25%/75%) with collagen, HA/TCP (25%/75%) without collagen, (HA/TCP)/PLGA (85%/15%) with collagen, (HA/TCP)/PLGA (65%/35%) with collagen and a commercially available (HA/TCP)/PLGA (50%/50%) (ReOss T, Intra-Lock International, Boca Raton, FL) was used as control. After 4 and 8 weeks, the retrieved samples were subjected to histomorphometrical analysis. Results: Histomorphometry presented no significant differences concerning the bone formation between the different groups at both 4 and 8 weeks. Evidently, the (HA/TCP)/PLGA (65%/35%) with collagen presented the least amount of soft tissue incorporation within the defect. The same group possessed higher amounts of bone graft material within the defect throughout the 8-week observation period, whereas the other groups seemed to decrease in volume from 4 to 8 weeks. Conclusion: Changing the PLGA percentage to 35% within the biphasic graft material seemed to maintain its volume and prevented soft tissue migration, which could be clinically beneficial.

- PURPOSE: The aim of this study was to report the outcomes of a treatment option of immediate loading with intraoral welding on only 4 implants for the restoration of patients with maxillary edentulism. MATERIALS AND METHODS: Seventeen consecutive patients were rehabilitated with 2 parallel and 2 tilted implants in the maxilla. Immediately after implant placement, angulated abutments were screwed on the implants to create better parallelism among the implants; thereafter, a titanium bar was intraorally welded to the welding pins to create a superstructure that rigidly splinted the implants. A fixed full-arch durable prosthesis was delivered on the same day of the surgery. The patients were followed for 26.5 months on average. RESULTS: During the follow-up time, 2 implants were lost giving an implant survival rate of 97%. Nonetheless, all the prostheses remained in function and the prosthetic success was 100%. CONCLUSIONS: The rehabilitation of the edentulous maxilla with an immediately loaded full-arch prosthesis, obtained through intraoral welding on only 4 implants, is a functionally and esthetically successful treatment.
