Objective: Implant – supported overdentures have been an effective method for the treatment of edentulous mandibles. However, the loading time after implant placement is still controversial. The purpose of the present study was to evaluate the effect of immediate loading implantswith mandibular overdenture using Ankylos Syncone telescopic copings for the treatment of edentulous. Materials and methods: This study was performed on 22 edentulous mandibular patients visiting Department of High Technique, National Hospital of Odonto – Stomatology at Ho Chi Minh city. Each patient received four interforaminal implants. Ankylos Syncone copings systems was used to connect prostheses and implant, which then received immediate loading. The primary response variables were success and failure rate of implants and prostheses. The peri-implant tissue condition and peri-implant crestal bone loss level on radiography were evaluated at six months (T6) and twelve months (T12) postsurgery. Results: There is no peri-implantitis at the follow-up points. The osseointegration rate after 12 months was 100%, while the success rate and survival rate of protheses were 91% and 100% respectively. The peri-implant crestal bone loss on radiography images from baseline (T0) to T6 was 0.07 (±0.22) mm and from T0 to T12 was 0.12 (±0.29) mm. Conclusion: Mandibular rehabilitation usingimmediate loading implant mandibular overdenture with Ankylos Syncone telescopic has shown a high success rate and patient sastisfation over time.

Abstract Immediate loading of endosseous implants is becoming a widespread therapeutic procedure for the rehabilitation of patients with edentulous jaws. The purpose of this prospective clinical trial was to evaluate the long-term success rate of endosseous implants placed in the edentulous lower jaw and loaded on either the same day of surgery or the next day. Nineteen patients were enrolled in the study. Eleven patients, accounting for 64 implants, received their provisional prosthesis the same day of implant placement, and 8 patients, accounting for 52 implants, were rehabilitated the day after surgery. All patients were rehabilitated by a hybrid prosthesis supported by 5 to 6 Osseotite implants. Two implants failed in the group of patients who had their implants loaded the same day (96.9% success rate), whereas 1 implant failed in the other group (98.1% success rate). The overall implant success rate was 97.4%. All failures occurred within 2 months of function. No other complication was reported. The mean follow-up for this interim report was 37.8 ± 16.5 months (range 8–65 months). Crestal bone loss was similar to that reported for standard delayed loading protocols. The results of this study suggest that the rehabilitation of the edentulous lower jaw by an immediate occlusally loaded implant-supported hybrid prosthesis is equally successful when loading is applied the same day or the day after implant placement. Immediate loading with 5 to 6 implant-supported prostheses represents a viable alternative treatment to classic delayed loading protocols.

As placement of implants into immediate sites involves management of the remaining root structure, these residual roots may be used as a guide for the development of osteotomy. This aids in implant positioning and prevents drill slippage into the residual root spaces during osteotomy drilling. Following completion of the osteotomy, the remaining root structure is extracted prior to implant placement into the site. The aim of this study is to assess the success rate of implants when the residual roots were used as anatomical guides for osteotomy. One hundred implants were placed in 57 patients, and 4 different types of implants were used: 47 Bioner TOP DM implants, 20 Nobel Biocare Replace implants, 25 Biohorizons Tapered Internal implants (Birmingham, Ala), and 8 Alpha-Bio Tec SPI Implants. The implants were placed into 57 patients. Osteotomies were placed through intact residual roots, which acted as anatomical guides for implant surgical placement. Patients had a follow-up period of 2 years, and in that time none reported discomfort after implant placement. There were no signs of peri-implantitis observed in any of the patients. Of all the implants placed, the Bioner TOP DM implant showed the least amount of crestal bone loss. Placing implants through residual roots as an anatomical guide is a useful technique that shows good results over a 2-year follow-up period.

Edentulous Jaws

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.

Objective: The purpose of this study was to evaluate the survival rate and the amount of periimplant bone loss in implants placed in free iliac graft following segmental mandible resection. Materials and Methods: Over a 5-year period between 2010 and 2015, nine patients with odontogenic tumors who were candidate for segmental mandible resection were enrolled in this study. Resection defect was immediately reconstructed with non-vascularized iliac graft and 4-6 months later 36 implants of 5 different brands were inserted in grafted mandibles. Information regarding implant survival, peri implant bone loss or inflammation for a mean follow up period of 33 months was obtained. Results: One implant was failed out of 36 implants and the cumulative survival rate of implants was 97.2% in this follow up period. There was no sign of peri implant inflammation or gingival recession or BOP in any patients. The cervical bone loss level varied between 0.6 to 12mm (the length of failed implant) with the average of 0.96 mm. The bone loss level of survived implants varied between 0.6to 1.72mm with average of 0.64mm. Conclusion: This study demonstrated that reconstruction of segmental mandibular defect with non vascularized iliac graft followed by dental implant placement is an effective and predictable method to restore oral function.

Achieving adequate fixation of bone blocks harvested from the mandibular symphysis and used in conjunction with dental implants has been a continuing challenge. In response, the Authors developed a method of using the implant itself to stabilize the graft material in single-implant sites in severely resorbed alveolar ridges. This technique was utilized to place 19 standard implants in 15 patients. After 12 to 60 months of clinical and radiological follow-up, all implants had survived, a success rate of 100%. Measurements of the radiographs showed bone loss of 1.70 mm ± 0.4 mm.

Bone Height

The purpose of this study is to estimate the magnitude of crestal bone loss and to identify factors associated with changes in crestal bone height following placement of dental implants. This was a retrospective cohort study, consisting of a sample derived from the population of patients who had at least 1 dental implant placed in a community practice over a 10-year period. A total of 11 predictor variables were grouped into demographic, related health status, anatomic, implant-specific, and operative categories. The primary outcome variable was a change in crestal bone height (mm) over the course of follow-up. The secondary outcome variable was crestal bone loss at 1 year grouped into 2 categories (bone loss >1.5 mm and ≤1.5 mm). Univariate and multivariate regression mixed-effects models were developed to identify variables associated with crestal bone level changes over time. P values ≤.05 were considered statistically significant. The study sample was composed of 85 subjects who received 148 implants. The mean change of the crestal bone was −2.1 ± 1.5 mm (range = −12.5 to 0.5 mm; median = −1.77 mm). In the multivariate model, none of the variables studied were statistically associated with mean crestal bone loss. Among 84 (66.1%) implants with bone loss >1.5 mm within 1 year, no variables were associated with bone loss in the multivariate model. Of the 11 predictor variables evaluated in this study, none were statistically significant with regard to an increased risk for crestal bone loss or for excessive bone loss within the first year after implant placement.

Abstract In the past decade, several investigators have reported that implants inserted in autografts in the same operation (ie, simultaneously inserted implants [SIIs]) have achieved excellent results. However, no report regarding SIIs placed in fresh frozen bone (FFB) is available. Thus, the authors planned a retrospective study on a series of SIIs placed in homologue FFB (but not immediately loaded) to evaluate their clinical outcome. In addition, a comparison with implants inserted in FFB in a second stage (ie, delayed inserted implants) was performed. Seventeen patients were grafted with FFB, and 48 implants were inserted in the same operation. Implant diameter and length ranged from 3.25 to 4.0 mm and from 10.0 to 15 mm, respectively. Data were compared with 302 implants inserted in FFB in a second operation during the same period in 64 patients. Analyzing SIIs, it was noted that only 3 implants were lost (ie, survival rate [SVR]  =  93.7%), and no differences were detected among the studied variables by using lost implants as a predictor of clinical outcome. On the contrary, by using crestal bone resorption around the implant's neck and specific cutoff values, it was possible to demonstrate that prosthetic restoration (ie, removable overdentures) correlated with a statistically significant lower delta insertion abutment junction (ie, reduced crestal bone loss) and thus with a better clinical outcome. By comparing SIIs with implants inserted in a second stage in FFB, a better outcome for delayed implants was demonstrated. Implants inserted simultaneously with FFB grafts had a high survival and success rate. SIIs inserted in FFB can be considered reliable devices, although a higher marginal bone loss is to be expected when fixed prosthetic restorations are used. Implants inserted in a second surgical stage have a better SVR and success rate than SIIs.
