Learn what each phase involves — pre-surgical orthodontics, the operation, recovery." updated: 2026-08-17T00:00:00Z publisher: Virtual Consultant Online --- Jaw Surgery Orthognathic Timeline # Orthognathic Surgery Timeline UK — What to Expect from Start to Finish Jaw surgery (orthognathic surgery) is typically preceded by 12–18 months of orthodontics and followed by a further 6–12 months of finishing treatment. The full process takes 2–3 years, but the surgical phase itself is one week in hospital and 6–8 weeks recovery.

The typical sequence involves: assessment and planning; pre-surgical orthodontic treatment (decompensation); surgical admission; immediate recovery; return to normal activities; and post-surgical orthodontic finishing followed by debond and retention. The entire process typically takes 2 to 3 years. Most of this time is spent on orthodontics, not surgery — the operation itself lasts several hours, and the hospital stay is usually 3 to 5 nights. A consultant orthodontist and a maxillofacial surgeon work jointly throughout, usually within an NHS hospital or specialist centre. In the UK, qualifying cases are funded by NHS England. ## Pre-surgical orthodontic phase (12–18 months) — decompensation Before surgery can take place, the teeth must be moved into a specific position that allows the jaws to be repositioned accurately. This process is called decompensation — the orthodontist moves the teeth away from the compensatory positions they have adopted over years of development in order to reveal the true extent of the jaw discrepancy. Counterintuitively, this can make the bite look and feel worse before it gets better. For example, in a Class III case (underbite), the lower front teeth may be retracted towards their true position, which temporarily worsens the visual relationship before surgery corrects the underlying jaw position. This phase uses fixed braces and typically takes 12 to 18 months. Patients are reviewed jointly by the orthodontist and surgeon throughout this phase. ## Surgical admission and the operation Surgery is performed under general anaesthetic in a hospital setting. The most common procedures are Le Fort I osteotomy (upper jaw repositioning), bilateral sagittal split osteotomy (BSSO, lower jaw repositioning), or both — bimaxillary surgery. The surgical team makes cuts in the jaw bones, moves them to the planned position, and secures them with titanium plates and screws. The operation typically lasts 3 to 6 hours depending on complexity. Patients are admitted the day before or morning of surgery and remain in hospital for 3 to 5 nights. Swelling begins immediately and peaks around day 3 to 4. Most patients describe the immediate post-operative period as uncomfortable rather than severely painful, and pain is managed with medication. ## Immediate post-operative recovery (first 2 weeks) The first two weeks following surgery are the most intense in terms of swelling, restricted mouth opening, and dietary limitation. Many patients are placed on a liquid or soft diet for the first 4 to 6 weeks, progressing to soft foods as healing allows. Bruising is common and may spread to the neck and chest. Numbness or altered sensation in the lower lip and chin is expected after BSSO and may take several months to resolve fully; in a small number of patients some altered sensation is permanent. Patients are typically signed off work for 2 to 3 weeks, though this varies with the type of work. Most patients are able to speak, though initial speech may be affected by swelling and elastics used to guide the bite. ## Return to eating, speaking, and activities By weeks 3 to 6, swelling reduces significantly and most patients progress to a soft food diet — pasta, fish, eggs, soft vegetables. Full normal diet is usually possible by 8 to 12 weeks. Contact sports and activities with a risk of facial impact are restricted for 3 to 6 months while the bone heals. The titanium fixation hardware is not routinely removed and causes no long-term problems. Speech typically returns to near-normal within 2 to 4 weeks as swelling reduces. The facial appearance changes significantly during this period as swelling resolves — the final aesthetic result may not be fully apparent for 6 to 12 months post-surgery. ## Post-surgical orthodontic finishing and debond After the surgical team confirms adequate bone healing — typically at 6 to 8 weeks post-surgery — orthodontic treatment recommences. This finishing phase focuses on settling the bite, closing any residual spaces, and achieving the fine detail of tooth alignment that was not possible pre-surgically. It typically takes 6 to 12 months. Elastics are commonly used in this phase to guide the bite into its final position. Debond (removal of fixed braces) is followed by fitting of permanent retainers — usually a bonded wire on the lower front teeth and a removable retainer for the upper arch. Retention is lifelong. Most patients who complete the full orthognathic pathway report significant improvements in function, appearance, and quality of life. ## Useful related pages [Jaw Surgery and Orthodontics UK](https://virtualconsultant.online/guides/jaw-surgery-orthodontics-uk) [NHS Adult Orthodontic Exceptions](https://virtualconsultant.online/guides/nhs-orthodontic-adult-exceptions-uk) [Functional Appliances UK](https://virtualconsultant.online/guides/functional-appliances-uk) [Retainers Complete Guide](https://virtualconsultant.online/guides/orthodontic-retainers-guide) [After Braces UK](https://virtualconsultant.online/guides/after-braces-uk) This guide is for general information only.

The full treatment pathway — from starting pre-surgical orthodontics to completing post-surgical finishing and going into retention — typically takes 2 to 3 years. The surgical phase itself is 3 to 5 nights in hospital, with 6 to 8 weeks of initial recovery. What is pre-surgical orthodontics? Pre-surgical orthodontics (decompensation) is the phase of treatment before jaw surgery in which fixed braces are used to move the teeth away from the positions they have adapted to over years. This makes the bite look temporarily worse but ensures the jaws can be moved to the correct position during surgery. It typically takes 12 to 18 months. Does the NHS cover orthognathic jaw surgery? Yes. NHS England commissions orthognathic surgery for adults with severe skeletal discrepancies where functional impairment is significant. Cases are assessed by a multidisciplinary team of orthodontists and maxillofacial surgeons through hospital-based services. Not all cases qualify — the decision is based on the functional need. How long is recovery from jaw surgery? Most patients take 2 to 3 weeks off work and social activities. Full dietary recovery to normal foods takes 8 to 12 weeks. Contact sport and high-impact activities are restricted for 3 to 6 months. The final aesthetic result may take 6 to 12 months to fully emerge as swelling resolves completely. When can I eat normally after jaw surgery? A liquid diet is typically required for the first 1 to 2 weeks, progressing to soft foods by weeks 3 to 6. Most patients can eat a normal unrestricted diet by 8 to 12 weeks post-surgery, depending on their healing and the extent of the procedure. Will I need more braces after jaw surgery? Yes. Post-surgical orthodontic finishing is a standard part of the orthognathic pathway. After the surgical team confirms adequate bone healing at 6 to 8 weeks, fixed braces are used to settle the bite and achieve the final tooth positions. This phase takes 6 to 12 months and is followed by permanent retention. Explore your options Quick links Not sure where to start?
