• Hello everyone, wanted to ask a question that came to my mind. My colleague was doing a lateral window sinus lift after elevating the membrane, he mentioned he saw a small perforation in the mesial aspect. He then placed a resorbable collagen membrane like a parachute and compacted a little bit of bone not applying to much pressure. He did a…

    • Hello Youssef, thank you for posting the question. Do you have any pictures of the CBCT?

      My understanding is that if the sinus membrane was stabilized, and you grafted it, and the patient has low contraindications, blood clots are likely to turn into bone.

      • I agree I think bone will form but it will take a long time to mature. If you wait only 6 mo the density may still be low. It is also possible to loose some height.

    • Hello everyone,

      This patient attended wanting a full mouth rehabilitation over implants. I will perform an intraoral scan soon. Was wondering how you would approach this case?

      • Lots to discuss here and many different ways to approach. Fixed? Overdenture? Establish VDO and VDR. Ensure proper bone reduction and place with good AP spread. Even if lower over denture if bone width good I prefer to place 4 implants around 1st molars and canine areas.

        • Thank you for your response. She is looking for a fixed prosthesis. Initially what i wanted to do is make a digital wax up. How would you bring this to the mouth to evaluate all this? Wouldn’t you need to first extract all teeth followed by complete dentures then analyse?

        What’s ur opinion on short implants in the posterior region? Such as 7.5mm height

      • Which approach for sinus lift would you do here

        Hello everyone,

        As you can see over here the anatomy of the sinus is irregular as the residual bone height is a lot higher buccally and goes down slightly palatally

        In this case would you rather:

        1. Do a crestal sinus left approach and place a 4.6(wide diameter)x7.5mm implant. Increasing the diameter to compensate the height in that case…

      • Quite a challenging case here, what would you do for this lower anterior sector. The two lower central incisors were extracted 6 months ago and the area has healed but still vertical bone loss is observed. Here is a video of the cbct scan.

        Options to do:

        – extractions of lower laterals followed by vertical and horizontal bone grafting…

      • Hello everyone,

        These are osstem bone level implants which i placed 3 months ago. Upper right first premolar was immediate after extraction with grafting in the gap. 3 months after you can see some slight bone loss especially mesially of the upper premolar implant, would like to know the cause and how to prevent this? Also if implants are…

        • For the upper pre-molar, potentially, it may not have been deep enough. The x-ray does look like it could’ve been deep enough, but if there was some buccal or Palatal bone loss on the mesial then it may had to have been slightly deeper to compensate for that and if there’s too much bone loss on either of those walls, it would definitely be…

        • Another thing to consider is the proximity to the tooth anterior tooth. Did the anterior teeth have any perio-disease? Studies show that disease from neighboring teeth can extend up to 2mm outwards. This might be something to consider. Thanks for sharing!
