A Pilot Study to Determine the Effectiveness of Different Amoxicillin Regimens in Implant Surgery

The aim of this study was to attempt to determine the minimum effective regimen of amoxicillin antibiotic prophylaxis for dental implant surgery. One hundred patients were randomly allocated to 4 different antibiotic prophylactic treatment groups. At second-stage surgery, only 2 implants failed in the nonantibiotic group. No statistically significant differences were found in the 4 groups, probably because of the limited number of the samples. Until a study with a larger population may definitely rule on the role of antibiotics in oral implant surgery, in may be prudent for the practitioner to adopt the single preoperative antibiotic dose as the minimal effective regimen.

Buccal Plate Augmentation: A New Alternative to Socket Preservation

Alveolar ridge resorption occurs after tooth extraction and has the potential to either complicate implant placement or impair the final esthetic result. Techniques to preserve natural bone and soft tissue contours are of great interest to clinicians and patients because even subtle postextraction buccal plate resorption may have significant clinical effects, particularly in the esthetic zone. Buccal plate augmentation (BPA) is a novel approach for ridge preservation aiming to avoid recession of the facial wall of the socket without interfering with the natural healing mechanism of the extraction socket. It consists of placement of bone graft material over an intact buccal plate, underneath the soft tissues in a surgically created pouch with an aim to maintain or augment the soft tissue esthetics of the region.

Piezosurgery-Assisted, Flapless Split Crest Surgery for Implant Site Preparation

IntroductionBucco-lingual resorption of the alveolar ridge can, at times, be predictably corrected at the time of implant placement. Among the different options available to achieve this are a group of surgical techniques described as split crest or split ridge procedures. Most of these procedures require the use of a mallet and some type of chisels and/or osteotomes; they are very technique-sensitive and can be uncomfortable for patients. Recently, alternative tools to split the crest have been presented, and these include the newer bone expanders and the piezoelectric scalpel. A flapless approach to implant dentistry has become popular with the aim to alleviate post treatment side effects, accelerate healing and avoid bone resorption caused by flap elevation.MethodsWe present a technique combining the use of a piezoelectric scalpel and a tapered bone expander in a flapless fashion as a novel way to perform split crest procedures with an aim to optimize outcomes and acceptability by patients.ResultsAll implants were successfully placed and the resorbed ridge expanded in the same setting. Findings were confirmed by postoperative cone beam cat scan (CBCT) evaluation.ConclusionsThis new technique is a predictable approach for split crest procedures and has high acceptability by patients and is technically simple for surgeons.

A case report of bilateral mandibular vertical guided bone regeneration with and without bovine thrombin/calcium chloride activated platelet-rich plasma.

One patient with a bilateral vertical defect was treated on one side with guided bone regeneration (GBR) and an autologous bone graft and on the contralateral side with the addition of platelet-rich plasma (PRP). At the 6-month reentry, clinically and radiographically enough bone width and height were present to allow implant placement in both sites. At the same time point, at the histologic level, no differences were noticeable. Similar results were obtained in this case in vertical bone regeneration with and without bovine thrombin/calcium chloride activated PRP applied to GBR techniques.

Immediate Placement and Provisionalization With Buccal Plate Preservation: A Case Report of a New Technique

Abstract Abstract Post-extraction resorption of the alveolar ridge is known particularly to affect the buccal plate, increasing the risk of facial soft-tissue recession and other adverse clinical effects. The authors have developed a simple technique for buccal plate preservation that involves surgically creating a pouch facial to the buccal plate that is filled with xenograft material. This technique can also be utilized in cases for which immediate implant placement and provisionalization are planned. A case report illustrating this approach is presented.

Can Corticotomy (with or without bone grafting) Expand the Limits of Safe Orthodontic Therapy

Purpose To assess whether concomitant particulate bone grafting makes a difference in the ability to safely orthodontically reposition teeth outside the bony envelope after corticotomy. Material and methods Retrospective analysis of patients who underwent corticotomy as part of their orthodontic therapy for treatment of severe crowding. Patients were divided as: a) Group 1: corticotomy with bone grafting, and, b) Group 2: corticotomy without bone grafting. CT scan examinations were performed before and at the end of the treatment. Measurements of bone and tooth positions were obtained and differences between pre- and post-treatment values were calculated. Results The study sample included 20 adult patients between the ages of 25 to 58 years. A total of 144 teeth were orthodontically repositioned outside their native bony envelope after corticotomy. Average follow-up was 9 months. Teeth that were repositioned after corticotomy and bone grafting maintained the alveolar bone volume around them while corticotomy without bone grafting was not successful in maintaining bone thickness around teeth that were moved outside the alveolar housing. Conclusions Corticotomy in combination with guided bone regeneration has the potential to increase the scope of conventional orthodontic treatment by allowing for expansive movements beyond the traditional limits.
