Brief Summary

Materials and methods: fourteen patients were selected according to the inclusion criteria, the participants were stratified equally into two groups, patients were assigned to receive either monoplane or lingualized occlusal schemes to their overdentures. For each patient placement of two mini-implants in the mandible at the canine region was done, bar joint attachment was used to splint the mini implants. Each implant was 2.5 mm in diameter and 10 mm in length. T-scan occlusal load analysis records were done in centric occlusion , the records was used to analyze the biting force of the denture as a Full Closure Force Movie recording, then Time vs. Force Graph of that Force Movie is accomplished. T-scan records were taken three times for each patient in the two groups ,Immediately after loading ,three months and six months of loading.

Conditions

Dental Occlusion, Traumatic; Edentulous Alveolar Ridge

Outcome Measures

Primary Outcomes (1)

• traumatic dental occlusion by T-Scan III

  To evaluate the stress distribution in mandibular overdenture retained by two splinted mini implants using monoplane and lingualized occlusion in setting of teeth using T-Scan.
