Dental Implant surgery type. 1-stage or 2-stage?

Two stage is absolutely not cheaper from a cost perspective, in fact it will probably end up being marginally more given that you will need two appointments, local anesthesia x2, and instrument set up x 2 all which have some associated cost wit it.  If your bone is not optimal for a one stage procedure then a two stage procedure is likely a better solution.  Each surgeon has their preferences and reasons why based on there experience.  I have performed both single stage and 2 stage procedures but it is on a case by case basis.All the best

Hello!
Without x-rays it is difficult to determine if your implant placement could be done in one visit. Is there an infection? Does a tooth need to be extracted? Is there significant bone loss? Any of these would require your surgery be done in two parts. 
Step one would be to extract your tooth and fill in the space with bone and allow it to heal before placing the implant. Step two would be placement. Sometimes an implant can be placed at the time of the extraction depending on the site. We usually wait 3-5 months before placing a tooth on a single implant to allow the bone to integrate and heal with the implant. Restoring, (or placing a tooth) too soon can cause an implant to fail. A 2 stage process is definitely more money than a 1 stage.
Each dentist has a preferred method. It's always a good idea to get a few opinions, having each dentist explain clearly what their treatment method would be and why, before deciding who you want to go with. 
Best of luck!

I have a very high success rate with 2 stage implant placement.....meaning that I make a small flap and place the implant and leave alone for a number of months and place the crown @4-6 months later. Consider 98% success rate.Yes you can do things quicker but may increase complications which could result in loss of the implant prematurely although still rare...think 85% success rate.Healthcare is an art based in science and your doctor will give you their advice on repetitive success and the best avenue to those results....go with their recommendations or talk with another dentist for another opinion in person with radiographs etc..
