Replacing missing teeth by dental implant is one option used nowadays. It is important to estimate the success rate of this treatment and to consider main variable that influence the success rate of this treatment. Among these factors to be considered is Length and diameter of dental implant supplied by many manufacturer company. The position of dental implant in oral cavity and the nature and magnitude of the applied force during mastication and parafunctional habits are other factors to be consider during treatment. Objectives: The influence of diameter, length and position of dental implant on success rate of dental implant treatment. Materials and Method: Prospective study involve (697) patients. Age (18-77y) and involve male (387), female (310). The study was done in department of dental implantology in Al-Ramadi health center. The study was done between (2013-2017). The criteria used for assessment patient prior to implant surgery as follow: The patients with no systemic disease, good glycemic control, good oral hygiene, no periodontitis, abstain tobacco 2 weeks before surgery. 820 easy implant® by franch dental implants manufacturer with sandblast surface, cylindrical-conical with internal hexagon and morse taper connection are used to replace teeth. A variety of dental implant length and diameter is used as follow: Upper Central incisor 5×11.5, upper lateral incisors 5×8.5, upper canine 5×8.5, upper 1st premolar 4.3×11, upper 2nd premolar 4.3-8, upper molars 5×7.Lower central incisors 3.5×10, Lower lateral incisor 3.5×10.5, lower canine 3.5×11.5, lower 1st premolar 3.5×8, lower 2nd premolar 3.4×8, lower molars 4.5×7. The patients were followed during the study period clinically and radiographically. The success rate is recorded and compared. Results: The statistical analysis of the study in Table 2 & Figure 2, Figure 3 indicate that the higher survival rate was (75.0000 +/- 5.0000) in the AMX 3 area. The lower survival rate was (55.3333 +/- 5.05757) in PM 3 because of short and nonstandardized diameter of dental implant. There is significant difference in mean of survival rate at 0.05 level. Conclusion: The diameter, length and position of dental implant are among these factors that should be considered when we estimate the success rate of dental implant treatment.
