Guided implant surgery gained acceptance and credit in implant dentistry. The aim of this study is to find out and evaluate the relationship between implant size and success rate following computed tomography scan guided implant surgery. Sixty-four (36 females, 28 males) completely and partially edentulous patients aged between 42 and 65 years old were participated and fulfilled the inclusion criteria of the study. Two hundred and seventeen dental implants (length: 10, 11.5, and 13 mm; Diameter: 3.3, 3.75, and 4.2 mm) were placed using computed tomography scan guided implant surgery, 117 implants were placed in the maxilla, while 100 implants were placed in the mandible. The implants were evaluated for clinical parameters at 2, 4, and 12 weeks intervals after installation. The overall success rate was 95.4%. Clinical stability of the implant size (Diameter 3.3 mm, Length 10 mm) was the least as compared to other dimensions (P ≤ 0.05). Medium and large size implants (Diameter 3.75 and 4.2 mm, Length 11.5 and 13 mm) were the highest success rate in implant surgery. Implants width (diameter 3.3 mm) and length (10 mm) are best avoided in guided computed tomography surgery as compared with other implant sizes especially in atrophic bony areas. Computer-guided implant surgery remains exciting. Watchful planning and precise stability of the surgical guide are mandatory for successful protocol. Further investigations should be performed to assess such technique among dental patients from satisfactory point of view. Intensive cooperation between dentists and software engineering discipline should be aimed to maximize the success of such technique.
