Implant Surgery and Reconstruction
Implant surgery and reconstruction is the area of oral and maxillofacial surgery concerned with replacing missing teeth and rebuilding the supporting jawbone using endosseous dental implants. It rests on osseointegration — the direct structural and functional connection between living bone and a load-bearing titanium fixture — and extends to the grafting and reconstructive procedures needed when bone volume is insufficient.
Definition
Implant surgery and reconstruction is the surgical discipline of placing osseointegrated dental implants and performing the associated hard-tissue augmentation required to restore form and function in partially or fully edentulous jaws.
Scope
This area orients the reader to the biological and surgical principles that underpin dental implant treatment: how implants integrate with bone, how deficient ridges and the maxillary sinus are augmented to receive them, how placement is planned and executed, and how biological and technical complications are recognised. It is a reference overview that links to detailed topic entries rather than a procedural or clinical manual.
Sub-topics
Core questions
- What biological conditions allow a titanium fixture to osseointegrate and bear occlusal load?
- When and how is deficient alveolar bone augmented to permit implant placement?
- How are implant position, timing, and site selected relative to anatomy and the planned restoration?
- What biological and technical complications arise around implants, and how are they classified?
Key concepts
- Osseointegration
- Endosseous dental implant
- Alveolar ridge augmentation
- Guided bone regeneration
- Maxillary sinus floor elevation
- Primary stability
- Peri-implant tissues
- Prosthetically driven implant placement
Mechanisms
The area is built on osseointegration, the phenomenon described by Brånemark and formalised by Albrektsson and colleagues, in which bone forms in direct contact with a titanium surface without an intervening fibrous layer, allowing the implant to transmit functional load to the skeleton. Achieving and maintaining this contact requires adequate bone volume and quality, atraumatic surgery, control of micromotion through primary stability, and an undisturbed healing period; where bone is deficient, augmentation procedures rebuild the recipient site before or during placement.
Clinical relevance
Dental implants are a principal means of rehabilitating tooth loss, and understanding the surgical and biological basis of implant treatment is foundational for reading the implant literature and for appraising reconstructive options. This entry describes the field at a conceptual level and is not a substitute for individualized clinical assessment, surgical planning, or treatment advice.
Epidemiology
Tooth loss is common worldwide and increases with age, and implant-supported restorations have become a widely used rehabilitation strategy. Long-term cohort data such as the 15-year follow-up reported by Adell and colleagues established that osseointegrated implants can survive for many years, while consensus work on peri-implant diseases (Berglundh et al., 2018) documents that biological complications around implants are a recognised population-level concern.
History
The field originated with Per-Ingvar Brånemark's observation in the 1960s that titanium could bond intimately with bone, a finding he applied to anchoring dental prostheses. Albrektsson and co-workers set out the requirements for predictable osseointegration in 1981, the same year Adell and colleagues published long-term clinical results in the edentulous jaw. Subsequent decades added bone augmentation, sinus elevation, and guided regeneration to expand candidacy, and consensus classifications of peri-implant health and disease later matured the field's understanding of long-term biological outcomes.

Frequently asked questions
- What is osseointegration?
- It is the direct contact between living bone and the surface of a load-bearing implant, without an intervening fibrous tissue layer, which allows a dental implant to transmit functional load to the jaw.
- Why is bone grafting sometimes part of implant treatment?
- When the residual ridge or the area beneath the maxillary sinus lacks enough bone volume to house an implant, augmentation or sinus elevation procedures are used to rebuild the recipient site so an implant can be placed and integrate.
