Occlusion and Dis-Occlusion Time in Mandibular Overdentures Supported by Conventional Versus Mini- Dental Implants
Trial Parameters
Brief Summary
The aim of the study will be comparing between the occlusion and disocclusion time in mandibular single overdenture supported with immediately loaded two conventional implants versus immediately loaded four mini-implants. Research question Is there a difference in occlusion and disocclusion time between two mandibular single dentures, one supported by immediately loaded two conventional implants and the second one supported by immediately loaded four mini-implants? Primary outcome: occlusion and disocclusion time Secondary outcome: Kapur index The null hypothesis is that there is no difference between both treatment modalities on occlusion and disocclusion time.
Eligibility Criteria
Inclusion Criteria: * patients with completely edentulous mandibular ridges and fully dentate or partially dentate maxillary arch restored with fixed restoration, * enough inter-arch space to allow for prosthetic rehabilitation with lower implant-retained overdentures * good oral hygiene and motivation. Exclusion Criteria: * The excluded patients will be patients with major systemic diseases that may affect osseointegration as uncontrolled diabetes mellitus, pregnancy, patients under bisphosphonate treatment.
