Abstract

Introduction: Dental implants have become a treatment option widely used for replacement of lost teeth. Primary stability following implant placement is essential for ossseointegration and it is mainly affected by density and quantity of bone at the implant site.
Objectives: The aim of this study was to evaluate and compare the osseointegration between two types of dental implants with modified design features as regard to primary stability and bone density surrounding the self-drilling implants (Zinedent Tec-2 implant system) and the self-drilling compressive type implants (Roott -implant system) after delayed placement of the implants in upper anterior region.
Materials and methods: A randomized prospective clinical and radiographic trial conducted on ten patients were included in the study. The patients were indicated for dental implant placement in the upper anterior region. The patients were randomly allocated into two groups equally by simple random technique. The Presurgical  phasewas done by assessment of  the patients clinically and radiographically. The surgical phase for both groups included implant placement then measuring the primary stability of the implants using the periotest device. The follow-up phase comprised clinical evaluation of gingival condition, implant mobility. Radiographical evaluation was performed by measuring the bone density using digital periapical x-ray, densitometer block and Image J software. In the prosthetic phase, a porcelain fused to metal restoration was delivered.
Results: After comparing the results of primary stability and the bone density surrounding the implants of both groups, it was shown that the average of mean, median and standard deviation for group B (Roott -implant system) were greater than group A (Zinedent Tec-2 implant system) but the differences were statistically insignificant.
Conclusion: The self-drilling implants is a new modality for easier manipulation of implant insertion and less postoperative complications with good outcomes.
