Edentulous Jaw, Missing Teeth
Conditions
Brief summary
This study aims to assess the treatment outcomes (clinical, functional and subjective) of full arch rehabilitations supported by implants with or without an immediate loading protocol. In this randomized clinical trial 20 fully edentulous patients were treated with full arch rehabilitations on dental implants. In half of the sample, the implants were loaded immediately by means of abutments after emplacement of the implant; but in the counterparts these abutments were connected to implants two months after the surgery (conventional protocol), and until that time the dentures were retained by healing abutments. Treatment outcomes were assessed at 2, 6 and 12 months after surgery. Clinical outcomes were quantified on the basis of implant failure rate, marginal bone loss and the peri-implant gingival index. Functional outcomes were calculated according to masticatory performance, estimated by the mixed fraction of a two-coloured chewing gum after 5, 10 and 15 chewing strokes, by the occlusal force recorded by pressure-sensitive sheets and by the bioelectrical muscular activity. The subjective outcomes of the treatment were assessed using both the oral satisfaction scale (visual analogue scale) and the Spanish version of the Oral Health Impact Profile (OHIP-20).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mastication | One year after treatment | Mixing ability tests |
| Clinical Performance of Dental implants | One year after treatment | Implant failure rate |
| Oral health-related quality of life | One year after treatment | impact according to the OHIP-20 (Oral Health Impact Profile) instrument. The score range from 0 to 20, being 20 the worst outcome. |
| Area of Occlusal Occlusion | One year after treatment | According to pressure-sensitive colorimetric sheets it is recorded the area in square millimeters |
| Occlusal Load | One year after treatment | According to the pressure-sensitive colorimetric sheets , the load in both the anterior and posterior region of the arch are calculated. |
