This study evaluates and compares marginal bone level changes around dental implants with two different surface characteristics in patients with a history of periodontitis. Participants will receive dental implants and will be followed up for one year to assess bone level changes around the implants.

Patients with treated periodontitis who require dental implants will be divided into two groups based on implant surface type. Marginal bone level will be assessed radiographically at baseline, then at 3 months,6 months, and 12 months after implant placement. The study aims to determine whether implant surface characteristics influence marginal bone loss in periodontitis-susceptible patients over a one-year follow-up period.

Inclusion Criteria:

• Age ranged from 35 to 55 years old, with a history of periodontitis
• Presence of at least one edentulous space
• Presence of adequate bone volume to place implants and achieves primary implant stability without the need for bone reconstructive approaches
• Absence of systemic diseases

Exclusion Criteria:

• Presence of para-functional habits
• Chronic smokers or former smokers
• Pregnancy and lactation
• Any patient who is not willing to follow our treatment protocol
