What this trial studies

This observational study aims to assess the survival rate and crestal bone levels around implants placed in the esthetic zone using different loading protocols: delayed, progressive, or immediate. It focuses on fully dentulous individuals over 25 years old who have experienced mobility in their mandibular incisor teeth or have lost central incisors. The study will analyze various factors affecting implant success, including bone defects and the relationship between implants and surrounding tissues. Data will be collected from medical records, including implant specifications and follow-up evaluations.

Who should consider this trial

Good fit: Ideal candidates are fully dentulous individuals over 25 with mobility in mandibular incisor teeth or partially dentulous individuals missing central incisors.

Not a fit: Patients with less than one year of follow-up or those who do not meet the inclusion criteria will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the long-term success and durability of dental implants, leading to better patient outcomes.

How similar studies have performed: Previous studies have shown varying success rates with similar approaches, but this specific comparison of loading protocols is less commonly explored.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* fully dentulous people over 25 who complained of the mobility of 4 mandibular incisor teeth, or partially dentulous people who missed 2 mandibular central incisor teeth and had periodontally affected the neighboring lateral incisor teeth.
* These individuals were subsequently treated with 2 implants supporting FPDs and following a delayed, progressive, or immediate loading protocol
* Class 0 or 1 bone defects after tooth extraction, were only included in the study
* The medical records included data regarding implant type, width, and length, surgical procedure, annual hygienist treatments, radiographs, and implant insertion date

Exclusion Criteria:

* had less than 1 years of follow-up, had incomplete restorative or surgical data, had non-diagnostic radiographs, had more or less than 4 unit fixed partial denture
* patients did not present for annual follow-up visits to evaluate oral hygiene measures or treat mechanical or technical complications.
* Individuals with bone defects class 2, 3, 4, or 5 after mandibular lateral incisor tooth extraction were also excluded.
