Globally implant therapy is currently accepted as a predictable, viable and successful option to replace missing teeth. Ample studies have shown excellent survival and clinical success rates of dental implants for various indications.The correct three-dimensional (3D) positioning of an implant is considered a prerequisite for an optimal outcome.Computer assisted implant surgery maybe beneficial in patients with limited bone and proximity to anatomic structures.Therefore, the aim of this randomized controlled clinical trial is to investigate the accuracy of implant position achieved with static CAIP(Computer Assisted Implant Placement) and to compare this with the accuracy of conventional cast based partially guided implant placement(cPGIP).
Patients in need of replacement of missing teeth.
Mouth opening at least 30 mm.
Age>18 years.
Limited vertical or horizontal dimension of the alveolar ridge.
Heavy smokers (more than 10 cigarettes per day)
Uncontrolled diabetes
Metabolic bone disorders
History of radiotherapy of the head and neck
