Abstract:
Objective: This study was carried out to Evaluation Short dental implant in posterior atrophic partially edentulous mandible and maxilla .
Patients and methods: This study was conducted on patients with missed posterior teeth with sever bone resorption where there is no enough bone for placement of standard length implant, where 4mm ultra-short implant was placed .patients were divided into two groups; first group have short implant in maxilla, and second group have short implant in mandible. Alveolar ridge were measured bucco-lingually, implant stability quotient (ISQ), vertical and horizontal bone loss were assessed immediately and after 6 months postoperatively.
Results: The results of this study revealed that; After implant placement, there was a statistically significant difference in mean stability between both groups, where the mandibular group showed a statistically significant increase in mean stability. After 6 months, there was a statistically a significant difference in stability between both groups. Mandibular group showed a statistically significant increase in mean stability. After 3 and 6months, there was a statistically non-significant difference in mean bone loss between two groups.
Conclusion:Short implants considered as a viable treatment alternative in both maxilla and mandible in cases with sever alveolar bone resorbtion because short implants reduce the need for complex surgeries.
