THE IMPORTANCE OF THE COMPLETE STUDY OF THE RADIOLOGICAL EXAMINATION IN IMPLANTOLOGY

Abstract

The success of dental implant rehabilitation requires accurate preoperative surgical planning. To get this desired we need to use specific imaging to assist the planning that is based on the patients’s need an determined by clinical presentation and professional judgment to formulate a diagnosis. Specific considerations should include clinical complexity, regional anatomic considerations, potential risk of complications ans esthetic considerantions in the location of implants. The use of imaging modalities for presurgical dental implant planning should be adequate to provide information suppoting the next goals: To establis the morphologic characteristics of the residual alveolar ridge , that includes considerations of bone volume and quality, vertical bone height, horizontal width and endentulos saddl length determine the amount of bone volume availeble for implant placements. This information is necessary to correlate the availeble bone dimensions with the selection of number and physical dimensions of the dental implant. To determine the orientation of the residual alveolar ridge. The orientation and residual topography of the alveolar-basal bone complex should be assessed to determine deviations of the morphology of the residual alveolar ridge that compromise alignment of the implant fixture with respect to the prosthetic plan. To identify local anatomic or pathologic boundaries within the morphologhy of the residual alveolar ridge limiting implant placement. Numerous internal anatomic features of the jaws (nasopalatine fossa and canal, nasal fossa, mental foramen, submandibular gland fossa, inferior alveolar canal) compromise and limit implant fixture placement or risk involvemnt of adjacent structure. Anatomic anomalies and local phatologies (retained root tips, sinus disease or adjacent inflammatory processes) may also prevent or restrict implant placement.
