简要总结
This study aims to evaluate and compare the efficacy of four methods in achieving vertical and horizontal gingival tissue displacement to be captured by optical digital impression. Moreover, the effect of the gingival displacement methods on the periodontal tissues around the final restoration will be assessed.

入选标准
- •Patients having normal occlusion.
- •Good oral hygiene with no signs of periapical pathology or periodontal disease (plaque index score ≤10).
- •Clinically and radiographically healthy gingiva and periodontium around the abutments with no evidence of attachment loss.
- •Thick gingival biotype (determination using color coded probe).
- •Patient having natural teeth as opposing dentition.
- •Gingival sulcus of the abutment teeth (≤ 3mm).
- •Adequate abutment tooth length for retention without deep subgingival extension (not more than 0.5mm)
排除标准
- •Pregnancy, which prevents the use of diagnostic x-rays.
- •Parafunctional habits.
- •Mobility of abutment teeth.
- •Gingival Recession
- •Patient presenting allergy to materials being used.
- •Medical history that could affect their periodontal condition.
结局指标
主要结局
Horizontal displacement measurement
时间窗: up to one month
All measurements were obtained from the definitive digital impression by using dental intraoral scanner software. Horizontal displacement was measured as the distance from the most prominent point of the crest of the marginal gingiva to the finish line in the same crowns section (in the same plane).
Vertical Displacement measurement
时间窗: up to one month
All measurements were obtained from the definitive digital impression by using dental intraoral scanner software. Vertical displacement will be measured as the distance from the most prominent point of the finish line to the deepest point of gingival sulcus.
次要结局
- Gingival inflammation measurement(up to one month)
- Gingival Height loss measurement(up to one month)
- Dental plaque measurement(up to one month)
