This is one of the most common questions we get.
Bone Grafting depends on a per case basis. We are often replacing teeth of different sizes and shape, so an implant that is wider for a back tooth will be taking more force than a dental implant on a front tooth which would be more narrow. If we try and take shortcuts by placing a small implant on a back area we could be in trouble long term. Your bite force is incredibly strong (300-500 psi). You can imagine if a tooth can chip or break, then something that is man made can undergo the same kind of strain and also be prone to breaking.
The following photo is a good example of an area where if we tried to have a thin implant to support a new crown could lead to fracture problems later on. It is often better to rebuild the foundation, let it heal for 3-6 months before placing the implant in an ideal location.
