11. Horizontal Ridge Augmentation Using Titanium Tenting Screws Followed by Implant Placement
Many bone grafting methods have been proposed to reconstruct maxillary or mandibular edentulous ridges. The amount of resorption influences the outcome of any regeneration technique. Siebert classified ridge defects according to their morphology and severity.1 The “Siebert classification” has helped standardize communication among clinicians
in the selection and sequencing of reconstructive procedures designed to eliminate the classified defects. In addition to this classification, other factors (Table 1) should be included in considering the appropriate surgical technique.
19.The “Slam-Dunk” Implant – How Common Is It? A Report of 200 Consecutive Implants in a Military Treatment Population
Background: A “Slam-Dunk Implant” implies an easy case in which no initial site preparation is needed, no factors complicate placement, and a flapless approach may be used. But how common are such easy cases? How predictable is this assessment? Methods: A consecutive series of 200 implants in 161 patients (27 female, 134 male) was reviewed in a young and healthy military treatment population. Various complicating factors were examined, including those known beforehand, and those encountered during surgery.
31. Clinical Performance of Implant Supported All-Ceramic Restorations Using Ceramic Abutments: A 1-3 Year Follow Up Study
Titanium has been considered traditionally as the material of choice for implant abutments because of its well documented biocompatibility and mechanical properties. One of the challenges in implant dentistry is creating a gingival margin that resembles the appearance of its counterpart of a natural tooth. This can be difficult as titanium used in implants and abutments has color characteristics and light reflection properties that can compromise the appearance of the peri-implant gingival tissues.1 Moreover, titanium abutments and dental porcelains have different rates of thermal expansion and contraction, which makes fusing porcelain to titanium difficult.
41. Immunohistochemical Evaluation of the Effects of Propolis on Osseointegration of Dental Implants in Rabbit Tibia
Background: Dental implant is an artificial tooth root fixed into the jaws to hold a replacement tooth or bridge. Functional surface modifications by organic material such as propolis coating seem to enhance early peri-implant bone formation, enhancing the initial cell attachment. The aim of the study was to study the expression of osteocalcin and collagen I as bone formation markers in propolis coated and uncoated implant in interval periods( 1, 2, 4 and 6 weeks). Materials and Methods: Commercially pure Titanium (cpTi) implants, coated with propolis
protein, were placed in the tibias of 40 New Zealand white rabbits, histological and immunohistochemical tests for detection of expression of osteocalcin and collagen I were performed on all the implants of both control and experimental groups for (1,2,4 and 6 weeks) healing intervals.
