Morphometric analysis of fibular graft dimensions for placement of dental implants

Abstract

IntroductionSurgical resections in the maxilla and mandible due to varied etiologies may lead to significant facial deformities, altered oral functions and subsequent psychological problems, raising the need for advanced reconstruction techniques. The goal of reconstruction being establishment of mandibular continuity with acceptable cosmetic result, establishment of osseous alveolar base for further dental rehabilitation and correction of soft tissue defect.The present study was aimed for observing the length of the fibular graft with maximum height and width along which the implants with bigger diameter and maximum height can be fitted. MethodsThe study was conducted on thirty dry human fibula bones. The mean length of fibular bone extending from the styloid process to the lateral malleollus was calculated. The mean width at the midpoint was recorded. The mean width of the medial, lateral and posterior surfaces was assessed for compatibility of different standard commercially available dental implant systems. ResultsThe study recorded the mean length of the fibula (X–Y) as 35.58 cm, ranging between 32 and 40 cm. Mean length of the bone available for graft (W–Z) is recorded as 16.72 cm. The mean width at the midpoint (A) being 12.83 mm. DiscussionThe maximum width and height of the fibula existed from a point 30 mm proximal to the mid point and 20 mm distal to the mid point and fibular graft if procured between these two points will provide us with maximum width and height. This knowledge would help the maxillofacial surgeons to procure the vascularised graft.
