What graft materials can you use in the sinus lift?
You can place almost anything into the sinus because it has excellent bone regeneration ability. Things as simple as collagen sponges have shown success. Some show good results with nothing at all, for samples of that check references 8-13 Rajkumar 2013
Technique. to add 2-3mm 4mm max (Bill’s thoughts) more go lateral
Follow these 3 rules create = success rates older study. I think all 3 are too conservative now
- If 6mm or more of bone go crestal and place implant (maybe less) some say down to 3-4mm
- 4-6mm lateral and place implant
- <4mm lateral 2 step 1
Lateral exclusions 1
- Long term Abs >2weeks within last 3 months
- Bone metabolism drugs
- 10 or more cigarettes a day
- Pregnant or trying to get pregnant
- Mucocutaneous disease
- Severe acute or chronic sinus pathology (sarcoidosis, osteomas, carcinomas)
- History cancer or radiation to head or neck in last 18 months
- Chemo in past 12 months
Risk factors of failure of graft 1
- Smoking 15 cigarettes a day
- < 4mm bone
- age 1
- alcohol intake
- residual ridge
- hx periodontitis
Osteotome-mediated sinus floor elevation
- Prep to 2mm floor
- Up fracture with flat end osteotome
- Pack graft material in with osteotome
Hydrodynamic piezoelectric internal sinus elevation
- Prep close
- Ultrasonic breaks floor
- Valsalva to eval
- Sinus membrane elevation with hydraulic pressure
- Inject metronidazole infusion (1/20 of common 200mg tab)
- Valsalva to eject fluid Bensaha 2012
- Graft with fibrin rich CGF Kim 2014 Sohn 2011
- Albert’s BSB Hammerless crestal lift kit to get into the sinus – just breaching the bony floor.
- Take some PRF “slug” and cut it into about 4 pieces.
- Take some fine tweezers (non-toothed forceps) and bring a piece of slug up to the osteotomy.
- Use YOUR plugger, with the depth stop (one size shorter than the
drill stop last used) attached, and use that to push the the piece of
slug into the hole.
- Repeat until you’ve rammed at least one full slug (more if it’s a big lift) into the hole.
- Take your final implant drill and set it for 50 rpm or less (my Bicon
background!) and drill through the sinus floor without irrigation,
knowing that the sinus lining has already been lifted up out of your
- Add more PRF into the osteotomy, pushing it in again with the plugger.
- Insert your implant.
Lateral or vertical get CBCT to find PSSA (posterior superior alveolar artery) lateral wall sinus
- Present 53% time
- Common to find during lateral approach of 1st molar
- Keep bony window under 15mm from alveolar crest
- Electrocauterize any bleed
- Terminate bleeding with Surgicel, digital pressure, and bone wax usually unsuccessful.
- Injection of local anesthetic with vasoconstrictor and electrocautery may be avoided due to the close proximity of the Schneiderian membrane
- Topical bovine Thrombin (King Pharmaceuticals, Bristol, TN) were applied to the surgical
- Within 5 minutes of thrombin hemostasis can be achieved.1

Lateral technique I like by Ioannis Vergoullis
Conclusions are based on few small trials, with short follow-up, and judged to be at high risk of bias. Therefore conclusions should be viewed as preliminary and interpreted with great caution. It is still unclear when sinus lift procedures are needed. 5 mm short implants can be successfully loaded in maxillary bone with a residual height of 4 to 6 mm but their long-term prognosis is unknown. Elevating the sinus lining in presence of 1 to 5 mm of residual bone height without the addition of a bone graft may be sufficient to regenerate new bone to allow rehabilitation with implant-supported prostheses. Bone substitutes might be successfully used as replacements for autogenous bone. If the residual alveolar bone height is 3 to 6 mm a crestal approach to lift the sinus lining, to place 8 mm implants may lead to fewer complications than a lateral window approach, to place implants at least 10 mm long. There is no evidence that PRP treatment improves the clinical outcome of sinus lift procedures with autogenous bone or bone substitutes.
Short implants (5 to 8 mm) may be as effective and cause fewer complications than longer implants placed using a more complex technique. It is not clear that bone graft materials are needed or
whether some bone graft materials are more effective than others. Biomaterials might be used in place of autogenous bone. There is no evidence to suggest factors extracted from the patients blood improve bone healing.
7 day Augmentin starting with loading dose 1 hour before.
Metronidazole 10mg once daily 7 day
CHX and Sinus precautions for 2 weeks
- Collagen membrane, BioXclude, epi-guide against membrane if tear (bad tear no implant)
- B-tricalcium phosphate
- Collagen or epi-guide over acess
- Ice packs to reduce swelling
- Nasal precautions 2 weeks
- Medrol dose pack
- Lateral window

- Acute sinusitis – Augmentin and Sinus care
- Sinus perf – squirt saline or local anaesthetic into the osteotomy and see if it comes back out or disappears or “Trampoline Test” or check 4 bubbles= Collagen membrane
- I place a bioXclude membrane then bone then implant.
- If the tear is a huge, gaping, black hole then the process changes. 😉
- In the situation described I most likely would have placed the implant and informed the patient of the increased risk of bleeding through their nose. Most of the time it will heal up just fine.
- if u suspect a torn membrane….would u just place some collagen product….dip it in gentamycin….and then still place ur implant?! no particulate grafts DT post
- Bleeding = electrocauterize, firm pressure, check above
- Post op bleeding = decongestant and AB
- Dehiscence = CHX 3times day and AB

Short 5 mm implants can be loaded in maxillary bone with a height of 4 to 6 mm, but the long-term prognosis is unknown. Sinus elevation alone may be successful in bone regeneration and crestal grafting may result in fewer complications than when using the lateral window approach. Bone substitutes may be possible to substitute for autogenous bone. The authors did agree that PRP treatment does not seem to improve the clinical outcome of sinus lift procedures with either autogenous bone or bone substitutes. = Oct 11
PRF created bone, my thought is prob don’t need anything in the lift
