The purpose of this study was to compare bone promotion around implants which were augmented with ePTFE membranes alone or in combination with cortical demineralized freeze-dried bone (DFDB) or the combination of platelet derived growth factor-BB (PDGF) and insulin like growth factor I (PDGF/IGF-I). Membranes were placed over titanium implants which had(More)
The purpose of this study was to examine the healing potential and re-osseointegration in peri-implant infection defects adjacent to various implant surfaces. In 7 female Beagle dogs, a total of 41 titanium oral implants (ITI, Straumann, Waldenburg; Switzerland) with a sink depth of 6 mm (diameter 2.8 mm) were placed transmucosally. Four different surface(More)
The cheek mucosa reacted to the implantation of cotton and silk with an aseptic inflammatory exudate which was found 24 hours and 4 days postoperatively. The leukocytic infiltrate was followed by a histiocytic reaction. Which was established at 7 days but which later progressively declined. The comparison of these findings with those previously obtained(More)
The purpose of this study was to test the bone-forming capacity of demineralized freeze-dried bone (DFDBA) and autologous bone grafts in extraction sockets. Seven paired sites were grafted with either DFDBA or autologous bone. The sites were reentered between 3 and 13 months for the purposes of obtaining biopsies of the grafted sites and to place endosseous(More)
Periodontal probing is commonly used for assessing both the status of gingival health and the connective tissue attachment level around teeth. The role of probing around endosseous implants still remains unclear. The purpose of this study was to determine the histological level of probe penetration in healthy and inflamed mucosal tissues around implants.(More)
The purpose of the present study was to assess in a clinical trial over 5 years the results following 4 different modalities of periodontal therapy (pocket elimination or reduction surgery, modified Widman flap surgery, subgingival curettage, and scaling and rool planing). 90 patients were treated. The treatment methods were applied on a random basis to(More)
BACKGROUND Maintenance of implants is imperative, since implants, like teeth, are susceptible to bacterial plaque accumulation and calculus formation, and thus at risk of developing peri-implant mucositis or peri-implantitis. METHODS This study determined the clinical effects of chlorhexidine treatment on peri-implant mucositis at 1 and 3 months as(More)
BACKGROUND The goal of this investigation was to histologically evaluate the healing and revascularization of the subepithelial connective tissue graft in dogs. METHODS Six beagle dogs were used in this study. Recession defects were surgically created on maxillary left P2 and right P2, and maxillary and mandibular left central and lateral incisors. The(More)
The aim of this study was to histologically evaluate and compare the treatment of ligature-induced peri-implantitis using guided bone regeneration, two bone grafts alone, or guided bone regeneration combined with one of the two bone graft materials. Mandibular premolars and first molars in seven beagle dogs were extracted. After placement of Brånemark(More)
BACKGROUND Correcting recession defects is one of the goals of periodontal therapy, and the efficacy and predictability of the various techniques are important considerations for both patients and clinicians. Several reports have examined the outcome of gingival recession treatment by means of coronally positioned flaps (CPF) and enamel matrix derivative(More)
