Purpose: The implant-abutment connection (microgap) influences the peri-implant bone morphology. However, it is unclear if different microgap configurations additionally modify bone reactions. This preliminary study aimed to radiographically monitor peri-implant bone levels in two different microgap configurations during 3 months of nonsubmerged he...
Purpose: The vertical location of the implant-abutment connection influences the subsequent reaction of the peri-implant bone. It is not known, however, whether any additional influence is exerted by different microgap configurations. Therefore, the radiographic bone reactions of two different implant systems were monitored for 6 months.

The aim of the present investigation was to histologically analyze the effect of using lyophilized bovine bone (GenOx® organic matrix) with (or without) guided tissue regeneration (using a decalcified cortical osseous membrane [GenDerm®]) on bone healing in surgically created critical-size defects created in rat tibia.
Surgical critical-size bone d...
The purpose of this study was to compare the quantity and quality of platelets in platelet-rich plasma (PRP) samples prepared using either the single- or the double-centrifugation protocol.
Ten adult white New Zealand rabbits were used. Ten ml of blood were drawn from each animal via cardiac puncture. Each blood sample was divided into two equal pa...
Purpose: It is unknown whether different microgap configurations can cause different peri-implant bone reactions. Therefore, this study sought to compare the peri-implant bone morphologies of two implant systems with different implant-abutment connections.
Materials and methods: Three months after mandibular tooth extractions in six mongrel dogs, t...
Introduction and objective:The purpose of this study was to evaluatethe concentrations of platelets obtained from platelet rich plasma (PRP) prepared according to the double-centrifugation protocol. Material and methods: Eight adult male rabbits (White New Zealand) weighing 2.8 to 4 kg were used.After general anesthesia, 10 ml of blood were drawn f...
This study histologically analysed the effect of autogenous platelet-rich plasma (PRP), prepared according to a new semiautomatic system, on healing of autogenous bone (AB) grafts placed in surgically created critical-size defects (CSD) in rabbit calvaria.
Sixty rabbits were divided into three groups: C, AB and AB/PRP. A CSD was created in the calv...
Introduction and objective:The purpose of this study was to evaluate a single-centrifugation protocol to prepare platelet-rich plasma (PRP). Material and methods:Ten white adult male (New Zealand)rabbits weighing 2.8 to 4 kg were used. After general anesthesia, 10 ml of blood were drawn from each animal via cardiac puncture. Each blood sample was c...
Introduction: Occlusal trauma is defined as an injury resulting intissues changes within the attachment apparatus as result of occlusalforce(s). Since 1901, when Karolyi reported a possible interactionbetween occlusal disharmony and periodontal alterations, severalstudies have tried to find scientific evidence that corroborates or not this interrel...

This case report describes a technique that uses a palatal mucosal graft and an acrylic resin postoperative stent in an attempt to increase the layer of keratinized tissue around osseointegrated implants in an atrophic mandible. During second-stage surgery, a split-thickness labial flap is reflected and apically repositioned by being sutured onto t...

It is unknown, however, whether different microgap configurations cause different bone reactions. Therefore, in this study the bone morphologies of two different implant systems were compared.

Severely resorbed mandibles often present a short band of keratinized tissue associated with a shallow vestibule. As a result, prominent muscle insertions are present, especially in the mental region of the mandible. This case report describes the deepening of the vestibular sulcus in an atrophic mandible by combining free gingival grafts harvested...
The purpose of this study was to histologically analyze the influence of bioactive glass and/or acellular dermal matrix on bone healing in surgically created defects in the tibiae of 64 rats (Rattus norvegicus, albinus, Wistar).
A 4-mm x 3-mm unicortical defect was created on the anterolateral surface of the tibia. Animals were divided into 4 group...
The purpose of this study was to analyze histologically the influence of platelet-rich plasma (PRP) coagulated with two different activators on bone healing in surgically created critical-size defects (CSD) in rat calvaria.
Forty-eight rats were divided into three groups: C, PRP-C and PRP-T. An 8 mm diameter CSD was created in the calvarium of each...
Primary bone grafts in congenital cleft alveolus do not always provide sufficient bulk or height of bone for ideal placement of endosseous implants. Thus, maxillary sinus or nasal floor elevation and inlay bone grafts in previously grafted areas are not exceptions in the daily routine. This case report stresses the need of a detailed treatment plan...
The purpose of this study was to histologically evaluate the healing of surgically created Class II furcation defects treated using an autogenous bone (AB) graft with or without a calcium sulfate (CS) barrier.
The second, third, and fourth mandibular premolars (P2, P3, and P4) of six mongrel dogs were used in this study. Class II furcation defects...
The purpose of this study was to histologically analyze the influence of bioactive glass and/or a calcium sulfate barrier on bone healing in surgically created defects in rat tibias.
Sixty-four rats were divided into 4 groups: C (control), CS (calcium sulfate), BG (bioactive glass), and BG/CS (bioactive glass/calcium sulfate). A surgical defect was...
The purpose of this study was to histologically evaluate the healing of experimental dehiscence defects after surface demineralization with tetracycline hydrochloride.
Six adult male monkeys (Cebus apella) were used in this study. Dehiscence defects were surgically created on the buccal aspect of the mandibular lateral incisors in all animals. The...
