Master Title

Effect of different implant arrangement on peri-implant stresses under mandibular resilient telescopic overdenture. A comparative in-vitro study.

Master Abstract

This study was carried out on three educational transparent acrylic resin models of completely edentulous mandibular arch. Four implants were installed bilaterally in each model in the following positions: 1- the canine and first molar areas (Quadrilateral configuration), 2- the canine and second premolar areas (Curved configuration), 3- lateral and first premolar area (Linear configuration). A duplicate implant retained overdentures was constructed for each model; and resilient telescopic attachment was used for retention. Strain gauges were bonded mesially, distally, bucally and lingually around each implant. Strain gauge analysis was used to measure the periimplant strain. Universal loading testing machine was used to apply different loading conditions on the overdentures: 1-Bilateral loading 2- Unilateral loading and peri implant strains were measured during bilateral loading, unilateral loading on the loading side and unilateral loading on the non loading side. The results of this study revealed that: (1) Quadrilateral configuration of four implant placement showed the lowest peri implant strains followed by linear group and the highest strains was recorded with the curved group at different loading conditions. (2) Posterior implants showed higher peri implant strains than anterior implants at different loading conditions (3) Comparing different peri implant sites, lingual site had the highest stresses followed by buccal, distal and the mesial had the lowest. Summary and Conclusion - 115 - From results of this study, it can be concluded that: 1- Arrangement of four implants in the mandibular arch with resilient telescopic attachment in a quadrilateral configuration (two implants at canine area and two implants at molar area bilaterally) provide the best load distribution under the overdenture. 2- Regardless the arrangement of the four implants with resilient telescopic attachment for mandibular overdenture the posterior implants showed higher peri-implant strains than the anterior implants. 3- Future studies are recommended to compare peri-implant strains with rigid and resilient telescopic attachments of mandibular overdentures with different implant positions and configurations.

PHD Title

Effect of Low Level Laser Therapy on osseointegration of Implant retained Mandibular Overdenture in Controlled Diabetic patients

PHD Abstract

This study was carried out to evaluate the effect of LLLT on implant osseointegration by evaluating implant stability as well as marginal bone height in controlled diabetic patients. Ten patients were selected from among those attending the out-patient clinic, Prosthodontic Department, Faculty of Dentistry, Ain Shams University to participate in this study. Patients were precisely selected and thoroughly examined in an attempt to reduce human variables and eliminate any factor that might adversely affect the results of this study. Patients were rehabilitated by maxillary complete denture and mandibular implant overdenture. Standard clinical and laboratory techniques were followed in denture construction for all patients. Patients participating in this study were randomly divided into two equal groups. Group A: implants of patients in this group were not exposed to LLLT (control group). Group B: Implants of patients in this group received LLLT at a predetermined exposure protocol (study group). Surgical installation of the implant was performed under strict aseptic conditions and immediate loading protocol was followed. Patients were recalled frequently for post-insertion inspection and adjustments as well as for LLLT therapy in group B. Follow-up visits were scheduled at the time of denture insertion, six and twelve months after implant installation for inspection of the prosthesis, implant stability evaluation via periotest® and radiographic evaluation of the peri-implant marginal bone height changes evaluation by CBCT. Summary ? 114 Results obtained from this study showed: ? Implant stability evaluation: o Study group recorded significantly better overall PTVs compared to control group. o Study group recorded significant PTVs compared to control group at loading only, however no difference in PTVs was observed between groups after 6 and 12 months. ? Marginal bone height: o Marginal bone height was significantly lower at 12 months than at 6 months in both groups. o Control group recorded significantly higher mean marginal bone height than study group.
