Eligibility

Sex/Gender

All

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: - Need for extraction and immediate implantation of a tooth in the aesthetic maxillary region (teeth 13-23). - Good overall oral health (no untreated periodontal diseases, no active inflammation, bleeding, or excessive plaque accumulation). - Regular oral hygiene and follow-up appointments. - Acceptable soft tissue profile without the need for additional augmentation. - Intact buccal bone plate for immediate implantation. - A torque of at least 30 Ncm to allow for immediate loading.

Exclusion criteria

Exclusion criteria: - Systemic and local health conditions: Active infections at the planned implantation site, use of medications that affect bone metabolism (e.g., steroids or bisphosphonates). - Heavy smoking (more than 5 cigarettes per day). - Poorly controlled diabetes mellitus (HbA1c > 7). - Severe form of bruxism.

Design outcomes

Primary

Measure	Time frame
- Change in marginal bone levels (in millimeters) around the implants after 1, 3, 6, and 12 months and at 10 years, measured using standardized radiographs. - Implant survival rate after 10 years (percentage of implants without explantation or significant clinical failure).	—

Secondary

Measure	Time frame
- Evaluation of peri-implant esthetics using the Pink Esthetic Score (PES; scale 0-14 points), particularly focusing on soft tissue integration and natural esthetics. - Assessment of patient satisfaction regarding function, comfort, and esthetics using a validated questionnaire (OHIP-49).	—
