Alveoloplasty is a surgical procedure in which a clinician reshapes and contours the alveolar bone — the tooth-bearing ridge of the jaw — to create a smooth, even surface for prosthetic fitting or to facilitate optimal post-extraction healing.
The procedure is most commonly performed alongside or shortly after multiple tooth extractions, particularly when a patient is transitioning to complete or partial dentures. Irregular bony prominences, sharp ridges, or undercuts remaining after extractions can make prosthetic seating difficult and painful; alveoloplasty addresses these anatomical obstacles before they become long-term problems.
Why It Matters
An uneven alveolar ridge can prevent dentures from fitting securely, leading to sore spots, instability during chewing, and accelerated bone resorption beneath the prosthesis. By recontouring the bone at the time of surgery, clinicians reduce the likelihood of these complications and shorten the adjustment period after prosthetic delivery. When implant-supported restorations are planned, alveoloplasty may also help level the site and optimize conditions for osseointegration.
What the Procedure Involves
- Incision and flap reflection: The mucoperiosteal tissue overlying the ridge is elevated to expose the underlying bone.
- Bone recontouring: Rongeurs, bone files, or rotary instruments remove sharp projections and smooth the alveolar crest.
- Irrigation: The surgical site is thoroughly flushed to clear bone debris and reduce infection risk.
- Flap closure: The soft tissue is repositioned and sutured, allowing the ridge to heal evenly.
- Follow-up assessment: The ridge is re-evaluated after soft-tissue maturation, before final prosthetic impressions are taken.
Alveoloplasty is classified as either primary — performed simultaneously with extractions — or secondary, completed in a separate surgical visit after initial healing. Primary alveoloplasty is generally preferred because it reduces overall treatment time and minimizes the number of anesthetic appointments required.
The procedure is closely related to alveolectomy, which involves more aggressive removal of alveolar bone, but alveoloplasty is conservative by design, targeting only the irregularities that compromise prosthetic fit or healing. Clinicians must carefully balance adequate bone removal against preserving ridge height and volume, since residual ridge resorption continues over time regardless of initial contouring.
Thorough alveoloplasty at the time of surgery is a foundational step in prosthetic rehabilitation, directly influencing how comfortably and reliably a patient tolerates their restoration over the long term.
