Summary

. There is little information on the degree of crestal bone loss around 4 inter-foraminal implant-retained mandibular overdentures (OVDs) and the amount of bone remodelling on the anterior maxilla and posterior mandibule on long-term function, particularly with different distributions.

Detailed description

Numerous studies confirm the successful use of implants to retain prostheses in the edentulous atrophic mandible. It has been recommended by some authors that clinicians should use 3 or 4 implants in situations that require increased retention, such as high muscle attachment or prominent mylohyoid ridge. LOCATOR attachment as a retentive component has several advantages over other systems, Such as: dual retention through both external and internal mating surfaces, a self-aligning feature which is helpful in guiding patients when placing their denture. There is little information on the degree of crestal bone loss around 4 inter-foraminal implant-retained mandibular overdentures (OVDs) and the amount of bone remodelling on the anterior maxilla and posterior mandibule on long-term function, particularly with different distributions.

Conditions

• Bone Resorption

Interventions

Type	Name	Description
OTHER	observation	To compare the effect of the mandibular implant retained OVD using quadrilateral distribution (QD) versus linear distribution (LD) on posterior mandibular ridge resorption (PMandRR), anterior maxillary ridge resorption (AMaxRR), and changes to the crestal bone level around implants after 10 years of function.
