Crestal (Internal) Sinus Lift in Gurugram
A crestal, or internal, sinus lift reaches the thin sinus lining through the site prepared for an upper back-jaw implant. It may be considered when some bone is already present at that site; anatomy and examination guide suitability. Sinus augmentation may be discussed when the posterior upper jaw lacks sufficient bone beneath the sinus (an air space in the upper jaw). The decision is whether this route fits the available bone and implant plan, or whether another approach or restoration is more suitable. Dr. Supreet Kaur Sawhney, MDS, is a Senior Consultant – Oral & Maxillofacial Surgeon and Senior Implantologist with 20+ years of experience. She can relate the assessment to the tooth replacement being considered.

How internal access differs
Sinus augmentation raises the sinus-floor region to develop bone for selected posterior upper-jaw implants. With an internal approach, the lining is lifted through the implant preparation site, also called transcrestal access. Some existing bone at the planned site is needed. A lateral-window route is another way of accessing the area; the route comparison depends on anatomy and the implant plan.

The amount of bone present helps determine access and timing. Cambridge University Hospitals (CUH) describes internal access with implant placement in its pathway, while an external route may be staged or simultaneous when support permits. These are general pathway descriptions, not a promised schedule for an individual. A short implant, changed implant position, bridge or denture may also be discussed, each with separate eligibility considerations.

Procedure, risks and aftercare
Cambridge University Hospitals describes its pathway as usually keeping patients awake with local anaesthetic (medicine that numbs the area); sedation (medicine to help you relax) or general anaesthesia (when you are asleep) may be used for difficult or multiple procedures. This describes that hospital’s pathway, not a universal provider protocol. The treating team explains the plan for your case.
The thin sinus lining can tear (perforation); the team may need to repair it or postpone grafting. Other possible problems include sinus infection, graft material visible through the gum (exposure), bleeding or an opening between the mouth and sinus. These possibilities do not predict an individual outcome.
Medical conditions, medicines and smoking should be discussed before grafting. Ask which graft and membrane products may be used and whether their origin is human, animal-derived or synthetic; site, amount and preference guide the choice. A healed graft can still leave too little bone for the intended implant, and further augmentation may be needed. CUH describes a site check at about one week, with stitch removal if needed, before implant treatment continues; this is a hospital example, not a fixed timetable. After surgery, follow your surgeon’s instructions, including any restriction on nose blowing for a specified interval to avoid pressure, and the review plan. Contact the surgeon if pain or swelling worsens after the first two days, or for persistent bleeding, including continuous bright-red bleeding; the source distinguishes this from slower, dark-red oozing. Follow the local emergency instructions for your procedure.

What to clarify during assessment
Ask how much bone is present, why an internal approach that requires some existing bone is being considered, what restoration is planned, when implant placement might happen and which alternatives are reasonable. The answer depends on clinical examination and appropriate imaging.
