Brief 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.

Outcome Measures
Primary Outcomes (1)
Posterior mandibular ridge resorption (PMandRR)
The amount of PMandRR will be assessed using posterior area index on a panoramic x-ray which use specific landmarkds.
10 years retrospective study
Secondary Outcomes (1)
Anterior maxillary ridge resorption (AMaxRR)
10 years
Other Outcomes (1)
Crestal bone loss around implants
10 years
Study Arms (2)
Quadrilateral distribution group
Patients with quadrilateral distribution of implants
Linear distribution group
Patients with lineardistribution of implants
Interventions
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.
Eligibility Criteria
10 patients in each group. total number of patients 20.
You may qualify if:
- Patients with 4 implants in the inter-foraminal region.
- Patients treated by staff and students in the Master's program in Prosthodontics Department according to the following criteria:
- Edentulous maxilla and mandible for at least 1 year.
- Problems with retention and stability of the mandibular denture.
- Mandibular bone height between 15 and 25 mm.
You may not qualify if:
- Patients with relative contraindications, such as
- A history of para functional habits.
- Smokers more than 10 cigarettes per day.
- alcoholism.
- Patients with a history of radiation therapy in the head and neck region . • Patients within intravenous administrated bisphosphonates., chemotherapy, and mental disorders that could jeopardies their co-operation.
