Occlusion and Dis-Occlusion Time in Mandibular Overdentures Supported by Conventional Versus Mini- Dental Implants

Condition(s) studied

Investigational drug(s) / intervention(s)

mini dental implant: For group MI patient, four screw type one piece mini dental implants will be inserted in the predetermined implant sites in the symphesial region. The position of the two distal implants will be marked 6 mm mesial to each mental foramen. The position of the other two implants will be marked equidistant from the distal implants with and at least 5 mm apart

conventional dental implant: For group CI patient, two screw type conventional implants will be inserted in the symphesial region.

Study 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

Primary outcome measure(s)

• occlusion/dis occlusion time — 1 year
  Occlusal parameters: occlusion time (OT) and disocclusion time (DT) will be recorded for each patient. The patient will be asked to close on sensor in centric occlusion holding their teeth together for 1 to 3 seconds then start right eccentric movement until disoccluding their teeth. This will be repeated 4 times for the right excursion (DT-right) and 4 times for the left excursion (DT-left). OT, DT-right, and DT-left were then calculated by taking the averages of the recordings.
