Placing implants in the anterior zone can be tough. There aren't many textbooks out there that explain where to place the implant and why to get the best esthetic outcome
When placing an implant in lets say the #8 position for example what are the consideration? How much bone do you need? How deep do you place the implant for proper emergence profile? What is the proper mesial/distal/Buccal/lingual positioning of the implant during placement. Size selection etc??
thanks in advance

There appears to be various systems to fill extraction sockets after routine extractions to perserve the ridge height for possible implant placement in the future. What are the recommended system or materials that are simple, succesful and practical for most patients?
In Short what material or technique give you the best bone for implant placement?

Could you enlighten me on the flapless technique and its indications?
Whats the best system to do this with?
Whats the best indication and when do you avoid? What success rate is reported over flapping and placing?

I did a recent open sinus lift on a patient and placed a xenograft with the sinus with PRP. Patient came back one week later with puss coming from the flap and pressure pain in the sinus and temperature.  I managed it with amox 500mg 4 times a day and it is now two weeks later and the infection still has not cleared up.
What is the best way to clean out the graft? How would you manage the situation? Is it even possible to get all the graft out without damaging the membrane? 

I have a patient missing teeth #8 and #9. I am always vexed on whether to place two implants or one implant and cantilever.

I know the tarnow study says to place one and cantilever. What is your opinion. What parameters to you look at in determining when to place two or 1 implant?

I have patient 15 years old patient,who complain in gum pain (Fistula is in the furaction and is nonrestorable).
Tooth #19 had a RCT  done couple years ago, and now its failed and needs and extraction. On PA x-ray there is a 5-6 mm cyst on mesial root, distal 3-4 mm, and furcation is involvment, and tooth hopeless, and needs to be extracted.
When do you think best time to place implants in children? How do you know when a childs growth is complete and safe to place implants.
thank you.

There are a whole host of articles on how to repair a sinus membrane perforated during open sinus lift: Loma Linda Pouch, Pikos Membrane, Suturing, etc, etc, etc.

However, I have not seen any literature on how to handle a sinus tear during a close sinus approach? Can it be repaired? How do you repair it? How do you even know if it is perforated?

Piezosurgery seemed to have changed the way we are practicing. However, I think my counterparts have passed me by. I am strictly using it for Sinus lifts where it makes a huge difference in reducing Sinus Complications.
My counterparts use it in every aspect of surgery. I am not that confident in it? What and where are people using piezo in daily practice? Do you see a difference to your surgery or practice?
Thank you for reading

Sinus lifts are relatively a young procedure and I dont know if we truly know the risks or longterm success of sinus lifting.
Do you know a meta-analysis or other literatur about of success, indications or contraindications for sinus lifting and grafting?
