The 2 most common complications of reduction malarplasty are nonunion or malunion and cheek drooping. Because masseter muscle is attached from zygomatic process of the maxilla to inferior two thirds of the zygomatic arch, rigid fixation and intimate bone contact without creating a gap are crucial for reduction malarplasty.Mesial-clockwise rotation of the zygomaticomaxillary complex can produce ...

PURPOSE This study aimed to evaluate peri-implant bone reactions to dynamic and static loads in a rat model. MATERIALS AND METHODS Two cylindrical titanium implants were placed in the left tibia diaphysis of 39 rats, which were divided into three groups: static load for 4 weeks (S4), static load for 8 weeks (S8), and static load for 4 weeks followed by dynamic load for 4 weeks (S4D4). All imp...

BACKGROUND The distance from bone crest to contact point is only the most frequently studied of the many factors that influence whether interdental papilla are present. The purpose of this study was to discover the association between embrasure morphology and central papilla recession. METHODS The central papilla was visually assessed in 310 adults using paralleling periapical radiographs of ...

Histologic evaluation of a single immediately loaded titanium provisional implant that was in function for 18 months revealed 81.3% bone-to-implant contact of the surface evaluated, whereas 9.6% of the implant surface evaluated was opposed by marrow and 9.1% by connective tissue. The bone appeared to be in active remodeling stage and in close contact with the implant surface.

BACKGROUND Endosseous dental implants with rough surfaces have been designed to improve early healing, especially in areas of poor bone or insufficient bone quantity. The aim of this study was to histomorphometrically assess the bone-to-implant contact on 3 different rough-surfaced implants following guided bone regeneration. METHODS Mandibular premolars and first molars were extracted in 12 ...

conclusions the fixator-assisted lengthening plate technique helps to maintain the stability and alignment at both sides of an osteotomy during tibial elongation. it allows the early removal of the external fixator immediately after lengthening is completed. this technique can be applied in children with open physes and in patients with a narrow medullary canal who are unsuitable for limb lengt...

INTRODUCTION: Calcium Phosphates (CaPs) such as biomimetic hydroxyapatite (bHA) have been extensively used as bone substitutes due to their similarity to the mineral phase of bone. However, the success of bone graft and subsequently bone regeneration depends mainly on postimplaiting neovascularization/ angiogenesis process [1]. Therefore, the knowledge of endothelial cell behavior in contact wi...

The upper talocalcanean join (articulatio talocruralis)1 is the join of the shin bone (tibia) and the ankle bone (talus). The tibia and the ankle bone are in contact at the facies articularis inferior tibiae2 and the facies articularis superior trochleae tali3. In order to build protheses that simulate the motion of the UTJ we study the geometry of the two surfaces FAIT and FAST, respectively. ...

This article presents a histologic evaluation of three hydroxyapatite (HA)-coated root-form implants retrieved from humans after being in function for 3.5 to 11 years. If the coronal portion, where bone loss was observed clinically and radiographically, is excluded, all implants appeared to be well osseointegrated, with intimate contact between the surrounding bone and the coating. There was no...

The ALPS (Advanced Locking Plate System) fracture fixation system is a novel internal fracture fixation device designed and produced by Kyon Veterinary Surgical Products of Switzerland. Compared to conventional internal fixation systems the ALPS system is designed to reduce the rate of surgical infection, improve the rate of fracture healing, and improve surgical application versatility. All AL...
