Things worth knowing about "Alveolotomy"
Alveolotomy is a surgical dental procedure in which the jawbone is selectively modified to allow the removal of impacted or retained teeth.
What is an Alveolotomy?
Alveolotomy is a surgical procedure performed in oral and maxillofacial surgery and dental surgery. It involves the targeted opening or reshaping of the alveolar bone – the part of the jaw that houses the tooth roots – in order to remove teeth that cannot be extracted by conventional means. The procedure is most commonly performed to remove impacted wisdom teeth, which are teeth that are fully or partially enclosed within the jawbone.
Indications
An alveolotomy is indicated when a standard tooth extraction is not feasible. Common indications include:
- Impacted or retained teeth that have failed to erupt naturally
- Wisdom teeth positioned at an angle, horizontally, or deep within the bone
- Deeply fractured tooth roots that cannot be removed with a simple extraction
- Supernumerary teeth (hyperdontia) that are congenitally extra
- Orthodontic reasons, such as insufficient space in the dental arch
Procedure
Alveolotomy is typically performed under local anaesthesia. In some cases, such as anxious patients or complex clinical presentations, sedation or general anaesthesia may be used. The general steps include:
- Administration of local anaesthesia to numb the area
- Incision of the gum tissue (mucoperiosteal flap) to expose the underlying bone
- Bone reduction using surgical instruments or a drill to free the tooth
- Removal of the tooth or root fragments, sometimes after sectioning the tooth
- Wound closure by suturing the gum tissue
Aftercare and Healing
Proper aftercare following an alveolotomy is essential to prevent complications. Recommended measures include:
- Biting on a sterile gauze pad immediately after the procedure to control bleeding
- Applying a cold pack to the cheek to reduce swelling
- Taking prescribed pain relievers as directed by the dentist or surgeon
- Eating soft foods for the first few days after the procedure
- Avoiding smoking and alcohol, as these impair wound healing
- Rinsing with an antiseptic mouthwash as recommended by the dental professional
Soft tissue healing typically occurs within 1 to 2 weeks. Complete bone healing may take several months.
Possible Complications
As with any surgical procedure, complications are possible, though they are uncommon:
- Wound infection at the surgical site
- Dry socket (alveolar osteitis) – a painful healing complication in which the blood clot becomes dislodged from the socket
- Swelling and bruising in the jaw and cheek area
- Temporary numbness due to proximity to neighbouring nerve structures
- Rare: injury to adjacent teeth or the maxillary sinus
