The aim of the study was to evaluate the influence of the mucosal tissue thickness on the crestal bone resorption around dental implants during a year of follow-up. Nine patients of both sexes included in this study received 24 implants. Patients in
the sample were divided into two groups: group I (mucosa above 2 mm, and 12 implants), and group II (mucosa up to 2 mm, and 12 implants). Implants in each group were divided into two groups: a control where 6 implants were placed at the crest level, and a test where (6) implants were placed 2mm supracrestally. The results revealed that there was an increase in crestal bone loss in group 2 with statistically significant differences. To conclude, the initial thickness of mucosa at the time of implant placement affects crestal bone loss; increased bon loss occurs when the tissue thickness is 2 mm or less at the time of implant placement.
The aim of the study was to compare the clinical and radiographic
changes between conventional implant and immediate implant
placement after tooth extraction. Ten patients of both sexes( 6male,4
female) included in this study were received 20 impl
ants. Each patient
received two implants in the posterior region of the mandible . Dental
implants were installed in the same surgical procedure , One of the
implants was placed immediately after tooth extraction (test group )
and the other one was placed 6 months after the extraction (control
group ) .
