Mandibular Single Implant Overdenture: a Prospective Clinical Trial
- Conditions
- Edentulous
- Interventions
- Procedure: Denture implantation
- Registration Number
- NCT01421849
- Lead Sponsor
- University Hospital, Ghent
- Brief Summary
Study hypothesis: that there would be no difference in patient satisfaction among institutionalised older people before and after treatment with a mandibular single implant-retained overdenture.
In a preliminary phase, a new denture is made or the old denture is adapted to provide a well-fitting denture.
Eight weeks after insertion of the new denture a single implant is placed in the centre of the mandibula. If the level of primary stability is sufficient to enable the implant to resist micromovement, the implant is immediately loaded . If not, the implant is loaded after 6 to 12 weeks. Primary stability is assessed by the final seating torque and by the clinician's interpretation and tactile sense of primary stability. Before, during and after the treatment patient satisfaction and clinical outcomes are evaluated by a 20 item questionnaire and a clinical examination.

- Primary Outcome Measures
Name Time Method Patient satisfaction after insertion of the new complete dentures. 1 week after insertion of the new complete dentures. This will be measured by a questionnaire with 20 items.
Patient satisfaction after loading. 1 year after loading This will be measured by a questionnaire with 20 items.
Patient satisfaction post-surgical. 1 week post-surgical. This will be measured by a questionnaire with 20 items.
Patient satisfaction after loading the implant. 1 week after loading the implant. This will be measured by a questionnaire with 20 items.
Patient satisfaction after insertion of the complete dentures. 8 weeks after insertion of the complete dentures. This will be measured by a questionnaire with 20 items.
Patient satisfaction after surgical procedure, functional loading. 6-8 weeks after surgical procedure. This will be measured by a questionnaire with 20 items.
- Secondary Outcome Measures
Name Time Method Repair management: type (fracture, matrix replacement, patrix activation, mechanical problems of the abutment, replacement of denture, relining, adjustment without adding new material) and number. From 8 weeks after insertion of the complete dentures to 6 months after loading. Maintenance - oral hygiene: Implant abutment: plaque index according to Mombelli, presence of calculus. From 1 week after loading the implant to 6 months after loading. Denture related: soft tissue problems. From 1 week after insertion of the new complete dentures to 6 months after loading. Maintenance - oral hygiene: Dentures using the denture plaque index by Augsburger and Elahi. From 8 weeks after insertion of the complete dentures to 6 months after loading. Implant level : lost implants, loose implants, … From the first week post-surgical to 1 year after loading. Soft tissue level : Peri-implant inflammation, bleeding index, probing depth From the first week post-surgical to 1 year after loading.
