Conditions

This study aimed to examine the impact of immediate implant-supported mandibular overdentures with cusped or cuspless tooth on surrounding bone tissues. Oral Health

Interventions

The randomization of selected patients was by lottery selection after giving each patient a number in a list, and then randomly the 20 patients were divided into two groups, 10 patients for each group

Design outcomes

Primary

Measure	Time frame
Crestal bone loss observed over one year, at 3, 6, 9 and 12 months. The measurement of crestal bone loss by periapical radiographs was evaluated by the masial and distal marginal bone height around the abutments (implant) from the radiograph of each patient as follow; two points were marked one at apex of implant and anther at the tip of the implant, a line (A) was drown connecting the 2 points then the tangent (b) to the tip of tooth, marginal bone height was measured by a dial caliper from mesial and distal alveolar crest to line (b), and measurements on serial radiographs were compared and the results were statistically analyzed as mean and percent.	—

Secondary

Measure	Time frame
1. Periapical lesions measured in each cross-section from the widest and deepest part of the lesion by the researcher using a precision digital caliper with an accuracy of up to 0.01 mm, at 3, 6, 9 and 12 months. 2. Pain measured using visual analog scale (VAS) at 3, 6, 9 and 12 months 3. Neural sensibility measured using a pulp sensibility test, which includes an electric test, which extrapolates pulp health from sensory response, at 3, 6, 9 and 12 months 4. Mobility of implants measured according to the periotest, siemens dental bensheim, Germany at 3, 6, 9 and 12 months.	—
