简要总结
A total of 20 completely edentulouspatients (male & female) of age group 40-65 years will be selected based onthe clinical & radiographic examination. All the patients will be grouped into 2groups.
Group 1: 10 completely edentulous patients to be rehabilitatedwith conventional dentures.
Group 2: 10 completely edentulous patients to berehabilitated with two implant-supported overdentures placed in theinterforaminal region.
New complete dentures will befabricated for both group A & group B patients .Later, in group B patients, two single stage endosseous implants will be placed bilaterally in theinterforaminal region of the mandibular arch. The implants will be loaded with mandibular denture two weeks after theimplant placement. Panoramic radiographs for both group A &group B patients will be taken and compared to ascertain the possible bone loss at baseline,3 & 6 months.The method consisted of proportional area measurements of theposterior mandible. The change in Posterior Area Index (PAI) is calculated forboth the groups.
