The test of occlusal patterns and chewing force of the patient whom received mini dental implant retained mandibular over denture at different time by T scan and study of affectation the quality of life after treatment.

Phase 4

Active, not recruiting

• Conditions: Thai not limit age are interested for mini- implant placement to retained mandibular overdenture. But full mouth complete denture must be good condition and have balanced occlusion.; There have the change of the occlusion after mini- implant placement immediately loading and during time of use in case of mini- implant retained mandibular overdenture.

Local
1. Maxillary complete denture must have good marginal fit and retention with acceptable esthetics.
2. Mandibular complete denture must have proper marginal fit and its thickness at the areas of the implants must be at least 6 mm.
3. Occlusal plane of denture should be parallel to interpupillary line, ala-tragus line, balanced occlusion and no severe occlusal interference.
The title of research that concentrate at mandibular overdenture. Because of about the occlusal concepts when making implant-supported and implant-retained mandibular overdentures. The dentate or edentulous condition of the maxilla plays a significant role in this respect. If the maxilla is edentulous, balanced occlusion is indicated. It is stressed that detailed preimplant placement diagnosis and treatment planning are essential to obtain a high standard of treatment with overdenture supported and retained by implants31.
4. Oral hard and soft tissues without pathoses.
5. Implant site must reveal a zone of at least 4 mm of keratinised mucosal width. the keratinised mucosal width may be corrected simultaneously with the implant installation: vestibuloplasty or free gingival grafts.
6. Alveolar ridge width of at least 6 mm (measuring point 5 mm below the alveolar creast) is required the implant site (labio-lingual dimension).
7. Alveolar ridge height of at least 14 mm is required at the implant site (vertical dimension)
