Abstract

The most critical factor in determining which type of implant to be used would be the available bone of the patient. Usually a minimum of 5mm in the bone width and 8mm in the bone height is necessary to ensure primary implant stability and maintain the integrity of bone contact surface. Placement of implant is limited by the several anatomic strutures such as maxillary sinus, floor of the nose, inferior alveolar neurovascular bundle and nasopalatine foramen, etc. When severe resorption of alveolar ridge is encountered, implant placement would be a problematic procedure. A number of techniques to improve the poor anatomic situations have been proposed. This article reports 4 cases of patients using surgical procedures such as blade implant technique, cortical split technique in the anterior maxillary area, sinus lifting and lateral repositioning of inferior alveolar nerve, We treated dental implant candidates with unfavorable alveolar ridge utilizing various surgical techniques, resulted in successful rehabilitation of edentulous ridge.
