Description
Inclusion Criteria:
Mandibular posterior edentulous with the first premolar as the last standing abutment tooth bilaterally.
- All patients were edentulous for at least 6 months from the last extraction.
- The bone height of the alveolar ridge was not less than 12 mm above the inferior alveolar canal and the buccolingual width of the alveolar ridge at the prospective implant site was not less than 6 mm.
- The opposing arch was almost dentulous, and any missing teeth were restored using a fixed partial denture.
- Adequate interarch space at least 5mm between the opposing dentition and the mandibular edentulous space.
- Remaining teeth were in good periodontal condition.
- Maintaining good oral hygiene and were ready to cooperate throughout the study.
Exclusion Criteria:
Patients with active infection or inflammation or flabby tissue in the areas intended for implant placement.
- Those patients with systemic diseases that may influence soft or hard tissue healing.
- Patients with a history of radiation therapy in the head and neck region.
- Neurological or psychiatric handicap patients that could interfere with good oral hygiene.
- Heavy smokers and drug abusers.
- Patients with severe clenching or bruxism.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
marginal bone loss around implants
Time Frame: 12 months
|
Marginal bone level was measured from the implant shoulder to the first bone to implant contact on the mesial and distal sides of the implant on digital standardized periapical radiograph using the long cone paralleling technique
|
12 months
|
modified plaque index
Time Frame: 12 months
|
Plaque adherent to the implants was quantified at four surfaces: buccal, lingual, mesial, and distal using a plastic periodontal probe after air drying for the implant and gingiva. The four sides for each implant were scored 0-3 according to the following criteria: Score 0: No plaque detected. Score 1: Plaque can be detected by running a probe across the marginal surface of the implant. Score 2: Plaque can be seen by naked eye. Score 3: Abundance of plaque. |
12 months
|
modified bleeding index
Time Frame: 12 months
|
A plastic periodontal probe was passed along the gingival margin adjacent to the implant and the following scores were given according to Mombelli and Lang Score 0: No bleeding with slight pressure on the mucosa using periodontal probe. Score 1: Isolated bleeding spots visible. Score 2: Blood forms a confluent red line on margin. Score 3: Heavy or profuse bleeding |
12 months
|
probing depth
Time Frame: 12 months
|
., the peri- implant probing pocket depth is measured around the surfaces of the implants in four areas (mid-buccal, mid-lingual, med-mesial, mid-distal) using plastic periodontal probe* which was inserted with light force and parallel to long axis of implant
|
12 months
|
Secondary Outcome Measures

Time Frame: 12 months after loading
|
framework fracture, screw loosening, screw fracture and chipping or fracture of veneer layer
|
12 months after loading
