Sinus Lift Case: How Much Bone Height Are You Gaining?

Dr. I asks:
I need to place an implant in #3 area [maxillary right first molar; 1,6]. As you can see in the radiograph below, there is very limited bone height. My usual standard operating procedure is to do a maxillary sinus lift and bone graft using a lateral window approach. However, I have had mixed success using the MIS internal lift protocols and materials. There are some dentists who are claiming they can increase bone height by 6mm. If I can accomplish that predictably that would be my first choice. Are others here using this technique? Have you had consistent success with it? How much bone height are you gaining?

Simple USE the Dask system ( or SLA) either lateral or internal , once used you will see how much easier life can be .There is about 3 to 4 mm of bone more than enough for similtaneous placement . Peter

In my hands this is a small lateral lift with immediate placement. DASK, piezo, whatever makes it reliable for you. While you can gain 6 mm height by an indirect lift, you are pushing the envelope a bit. In this case the sinus floor is significantly slanted, so your indirect lift would have to be even greater towards the distal of the site. There is only two mm of alveolar height available in the distal of the site. An open - lateral window technique here should be quick and strait forward. Gaining primary stabilty should be no problem.

Statistically with this amount of bone the lateral window is the most predictable. Our lateral window method with a graft material that lifts the membrane as high as you like and facilitates implant integration when the implant is placed simultaneously is another way to treat this patient successfully.

I recomend to Use Bicon Ultra Short Implant wth a minimal internal sinus lift and you avoid the lateral sinus lift procedures. less risk and trauma for patients!

if you are afraid of tearing the schneiderian membrane better use the bicon short Implants, as short implants you would able to avoid vital structures, second minimize grafting procedure,third maximize placement possibilities and fourth patient acceptance....

I've done hundreds of lift. THe only predictable approach is lateral. If you have a CT and it looks like there is a nice think leathery membrane, then you can attempt the internal first. But, you should always be able to bail out to the lateral should you pref the membrane. If you you've done enough of these, you know there are a small number of membranes that will tear if you just look at them - they are so thin. I have never used BIcons, but I don't like them. Half the ones that have walked in my office done by others are in some stage of failure. Also the prosthetic connection fails too. I really don't think they are mainstream, just a novel idea from years ago that won't go away..

I dont think this neccesitates the lateral lift .... If I have width, I would do an internal lift and use a 4.5/8mm Bicon implant with Sinus Lift Abutment.

This is a classical case for a minimally invasive antral membrane balloon elevation.It should be done with simultaneous implant placement.

im agree with dr amit narang or we can place 4.6 * 6.6 from axiom implant

I thaink so, Bicon 4.5x 6 or 5x5 mm.minimal internal sinus lift. Implant place subcrestal bone 1-2 mm,(Total leght 6-8 mm)

Sir, By indirect or closed sinus floor lifting technique,three milimeters of bone is the maximum thickness that you will be able to add to your present bone.Even if you have already had a thickness of six milimeters, then what you get, is only nine milimeters of bone thickness, which is not even suitable for an eight milimeter long implant.Therefore, it seems logical to go for a lateral window open lifting technique.Je pense que ca marche bien.

Pourquoi pas? Je ne sais pas. Mais bien sur quelque chose: La place pour Bio-Oss est la boullion!!! Unresorbable Bio-Oss belongs to the soup!!!

Dr. Mehdi Jafarei, Actually you can gain alot more than 3 mm. I on a regular basis obtain 5 to 6 mm. You have dedicate time to get a feel for bone and the membrane. Also consider a socket lift. It is a wonderful method for maxillary molars.

i think the ideal is the lateral window approach , and if primary stability is gaied we go for one stabe placement , if not wait 4month then place the implant

lat lift this - why use short wide implants are only for those who cant lift a lateral window in experienced hands will take 20min max and simultaneous placement of a descent 11mm fixture - long term no issue and evidence based treatment - come on guys we should not be sold on manufacturer gimmicks learn to lat lift and they become like composites !

Hi have you ever heard about HPISE (hydrodynamic piezo internal sinus elevation)? I use it for not for a long time now, but I am sure it is the best way to do sinuslift - without lateral window! go: HPISE.com and see the videos! have a nice day! dr K

You have about 2-3 mm of bone hight as I can see on your x-rays. The latteral aproach will be the best treatment in your case. The internal lift may cause rapture of the membrane if you will place 8-10 mm implant. You must rase the floor up to 5-6 mm. With internal aproach that may cause rapture. You can raise the floor up to 2-3 mm with internal technique, otherwise you must go with external window. The company who sales the product they will tell you everything so you will buy it from them but it does't mean that it will work.

lateral window with simultaneous placement of the 11 mm implant of your choice. One of the easiest and most predictable treatments around.

the case is eminently suitable for the short bicon implant with an internal sinus lift. i do not know how someone could state that "he has never used bicons, but doesnt like them". surely not an objective opinion.(DR S) we have done scores of these cases over a twelve year oeriod in minimal bone with short bicon implants and they are all still there and fully functional.the comment re failure of the prosthetic connections is blatantly untrue and indicative of lack of understanding of the bicon system. all it takes for success is an open mind, some practical experience, and a paradigm shift in thinking.

Very interesting case: the available ridge as i can see on the x-ray image is at least 3-4 mm, but probably more (4-6 mm) because seems to be present a good palatal ramp. In cases with these features i always use a crestal approach using sequential drills (Cosci’s technique) with graft(human mineralized)and immediate implant placement. This approach is very easy, minimal invasive and predictable for me and other collegues using this mechanical technique.

hi! try to use the intralift system from piezotome. great results!i stopped doing lateral window sinus lifts. better for patients and surgeons as well. i am a fun of any procedure that elevates the membrane with hydraulic pressure. check also the physiolift ssystem from mectron or the balloon lift as dr Mazor uses it (not hydraulic but also efficient).i believe minimally invasive dentistry (when appropriate) is the future. the patients love the ''better'' surgeon, not the ''big'' one.

You might want to consider the intralock mini dental implant system and consult with Shatkin First lab. If this were my case I would place 2 MDL's and place the restoration immediately using the F.I.R.S.T. technique developed by Dr. Todd Shatkin in Buffalo NY.This would alleviate the need for any sinus lift procedure. Check it out!
