To be able to perform swift and powerful movements, ant mandible closer muscles are composed of two subpopulations of muscle fibres: fast fibres for rapid actions and slow fibres for forceful biting. All these fibres attach to a sturdy and complex apodeme which conveys force into the mandible base. Fast muscle fibres attach directly to the apodeme. Slow fibres may attach directly or insert at i...

BACKGROUND Mandibular reconstruction is performed after segmental mandibulectomy, and precise repositioning of the condylar head in the temporomandibular fossa is essential for maintaining preoperative occlusion. METHODS In cases without involvement of soft tissue around the mandibular bone, the autopolymer resin in a soft state is pressed against the lower border of the mandible and buccal a...

OBJECTIVES This study aims to evaluate if micro-CT can work as a method for the 3D assessment and analysis of cancellous bone by comparing micro-CT with undecalcified histological sections in OVX rats. METHODS The mandible and tibia of sham, ovariectomised (OVX) and zoledronate-injected ovariectomised (OVX-ZOL) rats were assessed morphometrically. Specimens were scanned by micro-CT. Undecalci...

Mandibles and teeth of ungulates have been extensively studied to discern the functional significance of their design. Grazing ungulates have deeper mandibles, longer coronoid processes, flatter incisor arcades, and more hypsodont molars in comparison to browsers. If the functional significance of both mandible and teeth shapes is well-established, it remains uncertain to what extent mandible s...

Nonresorbable, nonporous, particulate hydroxyapatite (HA) was implanted on the mandible in rabbits and stimulated electrically, 4 hours per day, during the first postoperative week. Stimulated and control implant sites were recovered 8 weeks postoperatively and examined histologically. The HA migrated into the mandible in the electrically treated specimens, and was routinely found in intimate a...

Treatment of an edentulous mandible is an important standard area of indication for implants. The aim of the present study was to discuss various aspects of this very important topic using a literature research and possibly derive a recommendation for hybrid prosthetic treatment of the edentulous mandible. Though evaluation of the literature produced a large number of publications with case his...

This study was aimed to produce a clinically applicable model of composite bone graft capable of treating CSBDs in the mandible with a single surgical procedure. Twelve male white New Zealand rabbits were divided into two groups: control, n=4, consisting of A (untreated) and B (BCP/FS); experimental, n=8, named C (BCP/FS) and D (BCP/FS+VEGF). A circular CSBD (8-mm Ø) was created on both sides o...

BACKGROUND High-quality mandibular reconstruction using vascularized free fibular graft is necessary to provide an osseointegrated dental implant and fixed denture. An appropriate crown-implant ratio is needed, and a good match between bones is extremely important. There are no articles describing the analysis and evaluation of both the fibula and mandible in the same patients. METHODS Comput...

BACKGROUND AND PURPOSE Conventional thinking among radiologists is that the mandible acts as a closed "ring" that needs to fracture at 2 points, though the frequency of multiple mandible fractures has been reported to be only as high as 67%. However, many of these studies did not use CT to confirm the presence of suggested fractures and excluded nondisplaced fractures. The purpose of this study...

BACKGROUND Virtual surgical planning (VSP) has contributed to a number of technical innovations in mandible reconstruction. We report on these innovations and the overall evolution of mandible reconstruction using free fibula flaps at our institution. METHODS We performed a retrospective chart review of all patients who underwent virtually planned free fibula flap reconstruction of the mandib...
