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.

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.

Implant Placement

Bones and teeth are the only structureswithin the body where calciumandphosphate participate asfunctional pillars. Despite their mineralnature, both organs are vital and dynamic. The aim was to remark the indications for alveolar augmentation after tooth extraction and prior the placement of endoosseous dental implants. The autograft, allograft, alloplast, and xenograftmaterials all have reported success, alone or in combination,for particulate bone augmentation. Theparticulate autograft is the gold standard for mostcraniofacial bone grafting, including the treatmentof dental implant–related defects. Advantages of alveolar ridge augmentation with sufficient bone volume to adjust for uncompromised and esthetic implant placement, renders these procedures more than effective for majority of patients. Surgical reconstruction of the tissues and the procedure of ridge augmentation and subsequent placement of dental implant are necessary.

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.

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 Edentulous ridges in the posterior maxilla are often compromised by reduced bone volume. This anatomic condition often limits dental implant placement of 10 mm in length without prior or simultaneous sinus augmentation. The osteotome technique is an alternative and conservative technique for sinus floor augmentation and immediate implant placement in the posterior region of the maxillary jaw. According to the relevant literature, the osteotome technique appears to be a predictable and safe method for augmenting bone at the sinus floor and to improve bone density and quality of the implant site sufficiently so that immediate loading is possible. A 46-year-old male patient was referred to the authors to replace the single upper premolar with an implant-supported crown restoration without interfering with the integrity and topography of the adjacent gingival tissues. Only one clinical study analyzed minimally invasive implant and sinus lift surgery with immediate loading. In that case report, the osteotomy was widened to its final diameter using a series of incrementally larger twist drills. In our clinical case, a series of incrementally larger diameter osteotomes improved bone density. This simplified treatment modality can make single tooth implant rehabilitation of the atrophic premolar maxilla region more accessible, and immediate loading is facilitated by improved bone density.
