Abstract

To evaluate the characteristics of jawbone density, soft tissue biotype, thickness and width of keratinized gingivae at implant sites. The case study on a cluster of 24 patients from 1-stage lateral sinus lift surgery with 33 dental implants performed. The highest prevalence of bone mineral density (BMD) type was D3 with a rate of 69.8%; The thick soft tissue and thin soft tissue accounted for 54.5% and 45.5% respectively; male patients had a higher percentage of thick tissue biotype with a rate of 59.1% while female patients had a higher percentage of thin tissue biotype with a rate of 54.5%; The mean thickness of keratinized gingivae was 2.7 ± 0.7 mm in the premolar group; 3.2 ± 0.3 mm in the molar group, the mean width of keratinized gingivae was 4.1 ± 0.7 mm for the premolar group; 5.2 ± 1.0 mm for the molar group. The BMD in the posterior maxillary region was mainly D3 type with a rate of 69.8%. The thick tissue biotype had a higher prevalence with a rate of 54.5%. There was no significant difference between males and females in soft tissue biotype. The mean thickness of keratinized gingivae was 2.7 ± 0.7 mm in the premolar group; 3.2 ± 0.3 mm in the molar group, the mean width of keratinized gingivae was 4.1 ± 0.7 mm for the premolar group; 5.2 ± 1.0 mm for the molar group. A statistically significant difference was found in the thickness and width of keratinized gingivae between premolar and molar groups.
