Mandibular First Molar

A new dental implant system was used to replace the mandibular right first molar tooth in an eleven-month-old mole/intact, utility trained German shepherd dog. The permanent mandibular right first molar tooth had been extracted as treatment for an extensive carious lesion when the dog was 9-months of age. There were no complications associated with placement of the dental implant. However, peri-implant osteomyelitis occurred secondary to a traumatic oral wound 6-months following implant placement. The 17-month postoperative examination indicated that the implant system used in this case could be maintained in a working dog that uses extreme bite forces. However, periodontal inflammation and vertical bone loss exposing the implant fixtures were noted during oral examination. Further clinical applications are required to determine if the periodontal inflammation and vertical bone loss noted in this case were complications associated with the implant, maturity of bone at the time of implant fixture placement, general biting/chewing forces placed on carnassial teeth, or the oral trauma that occurred 6-months following implant placement.

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.

Abstract Flapless dental implant placement is possible in selected patients but limited to those sites with adequate or augmentable attached gingiva and available bone volume and density. Inadequate attached gingiva, available bone, and bone density may be augmented by pre-, intra-, or postoperative procedures. Bone ridge contour can be approximated by using a described fast set polyvinyl siloxane site evaluation technique. Assuming adequate length and height, a bone width of 5 mm is usually acceptable for standard diameter implants (3.5–4.2 mm). However, implant placement in sites with parabolic shaped ridges may need to be placed deeper to avoid vertical bone loss and implant thread exposure. Inadequate bone volume, less than 5 mm of bone width, may be developed by ridge expansion (split ridge) techniques. With ridge expansion, complications may arise such as malposition and labyrinthine concussion. Malposition may be corrected intraoperatively or grafted for a later implant placement. Labyrinthine concussion is usually of short duration but may be treated with head maneuvers. Sites with 2 mm or less width of available bone may not be treated flaplessly and may be more appropriately treated with extracortical augmentation grafting.

Implant stability is relevant for the correct osseointegration and long-term success of dental implant treatments. The aim of this study has been to evaluate the influence of implant dimensions and position on primary and secondary stability of implants placed in maxilla using resonance frequency analysis. Thirty-one healthy patients who underwent dental implant placement were enrolled for the study. A total of 70 OsseoSpeed TX (Astra Tech Implant System—Dentsply Implants; Mölndal, Sweden) implants were placed. All implants have been placed according to a conventional two-stage surgical procedure according to the manufacturer instructions. Bone quality and implant stability quotient were recorded. Mean implant stability quotient (ISQ) at baseline (ISQ1) was statistically significant lower compared to 3-months post-implant placement (ISQ2) (p < 0.05). Initial implant stability was significantly higher with 4 mm diameter implants with respect to 3.5 mm. No differences were observed within maxilla regions. Implant length, diameter and maxillary regions have an influence on primary stability.

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 &gt;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 &gt;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.

Background: To investigate the middle-term effect on bone remodeling of different timings for different implant placement (immediate versus delayed). Methods: Patients with an anterior maxillary failing tooth were treated by single-crown supported by dental implant. Subjects were retrospectively analyzed for 3 years and assigned to one of two predictor groups: nine immediate versus 10 delayed implant placement (1–2 months after tooth extraction). The crestal bone loss around dental implants was measured with the cone beam computerized tomography by fusing pre-operative and post-operative data. Results: The percentage of volume loss registered at 1-year follow-up (%ΔV) was of 7.5% for the immediate group, which was significantly lower (p-values ≤ 0.0002) than the loss of 24.2% for the delayed group. At 3 years, there was a significant difference (p-values = 0.0291) between the two groups, respectively, with a volume loss of 14.6% and 27.1%. When different times were compared, the percentage of the volume loss for the immediate group was different (p-value = 0.0366) between the first and third year (7.5% and 14.6%, respectively). For the delayed group, no significant difference was registered between the 1- and 3-year follow-up. Conclusions: The bone loss around dental implant-supported single-crown with different timing of insertion appeared higher for the delayed group than the immediate group.

Mandibular First Molar

Background: The objective of this case series was to evaluate the efficacy of miniscrews to upright the lower second molar as a result of early loss of the lower first molar in order to permit rehabilitation by means of an implant-supported single crown. Methods: The case series included ten patients who each received a miniscrew placed distal of the second molar in order to straighten the tooth; the prosthetic space gained (sufficient to allow implant placement in the edentulous space) and the change in angulation obtained were analyzed. The changes produced by miniscrews were evaluated in radiographs. Results: Statistical analysis identified significant improvements in angulation (p = 0.005) and significant amounts of space gained (p = 0.005) as well as a strong correlation between these two parameters (r = −0.93; p < 0.001). Conclusions: The use of miniscrews alone without the intervention of other orthodontic methods to straighten a mesialized lower second molar in order to replace a missing first molar with an implant significantly improves both the angulation of the molar and the prosthetic space available.
