What this Trial Is About
The microthreaded and platform switched implants could control the stress in the suitable range. The splint would disturb the function. So it is necessary to know whether the splinted single-unit crowns is fit for the adjacent multi-implants. Outcome variables: Splinted single-unit crowns on one side implants and non-splinted single-unit crowns on the other side Materials and method: 80-100 consecutive implants in at least 20 patients would be included for implant- supported restorations in the posterior maxilla or mandibular. All patients would be in general good health. For every patient, the same posterior teeth had lost on both sides for more than 6 months. All patients were treated by the same qualified surgeon. Prosthetics procedure would be performed by an experienced prosthodontist. The two sides were allocated to the test or the control group according to the predefined computer-generated randomization table. Clinical evaluations and radiographic analysis were performed by an oral and maxillofacial radiologist who was not aware of the type of Prosthetics technique that was used.

Eligibility Criteria
You may qualify if you...
- Patients must be in general good health.
- Need fixed implant-supported prosthesis on both sides of the posterior upper or lower jaw, with at least two adjacent missing teeth from the first premolar to the second molar.
- Patients must be able to be followed for 36 months after prosthetic loading.
- Must have a wide enough bone ridge to allow placement of a 4mm platform implant with at least 8mm bone height.
- Same posterior teeth must have been missing on both sides for more than 6 months.
You will not qualify if you...

- Need for pre-surgical bone or soft tissue augmentation in the planned implant area.
- Uncontrolled pathological conditions in the mouth.
- History of radiation therapy in the head and neck area.
- History of chemotherapy within 5 years before surgery.
- Any systemic or local disease that could affect healing or implant integration.
