Brief Summary
This study is a long-term clinical follow-up of a previously conducted randomized trial comparing different levels of surgical guidance in dental implant placement. The follow-up phase aims to evaluate peri-implant clinical and radiographic outcomes over an extended observation period of up to 67 months. Clinical parameters and marginal bone level changes are assessed to determine whether the accuracy benefits observed at implant placement translate into favorable long-term biological outcomes.

Outcome Measures
Primary Outcomes (1)
Implant Survival
Long-term survival of dental implants placed in the four study arms defined in the IMP SMART 002 trial, evaluated as a direct temporal extension of the IMP SMART 002 protocol (OGYÉI approval number 2224-4/2019). Implant survival is defined as the implant remaining in situ and functional without removal.
Up to 67 months post-implant placement
Secondary Outcomes (8)
Long-Term Tolerability and Safety
Up to 67 months post-implant placement
Number of events of prosthodontic complications
From prosthetic delivery up to 67 months of follow-up
Oral Health-Related Quality of Life Assessed by the OHIP-14 Questionnaire
Up to 67 months post-implant placement
Marginal Bone Loss
From prosthetic delivery up to 67 months of follow-up

Eligibility Criteria
You may qualify if:
- Age between 18 and 75 years
- Partial edentulism in the maxilla or mandible involving 1-6 missing teeth, with no more than three adjacent missing teeth
- Clinical conditions suitable for implant placement as assessed by the investigator or principal investigator (adequate bone and soft tissue conditions and acceptable occlusion)
- Ability to communicate effectively with the investigators and willingness to comply with study procedures
- Provision of written informed consent
You may not qualify if:
- Pregnancy or breastfeeding
- Women of childbearing potential without adequate contraception (for radiological safety reasons)
- Conditions preventing safe intraoral manipulation (e.g., limited mouth opening, pronounced gag reflex)
- Current or previous bisphosphonate therapy
- History of radiotherapy involving the maxilla or mandible
- International normalized ratio (INR) \> 2.5
- Known HIV, hepatitis B, or hepatitis C infection
- Known allergy to any component of the implant or surgical guide system
- Poor oral hygiene
- Substance abuse
- Smoking
- Untreated periodontal disease
- Any systemic disease or condition judged by the principal investigator to pose an unacceptable risk to the participant or to compromise study completion
