Implants have to integrate with the surrounding bone before a tooth and crown is placed on it.
Type I bone is comparable to oak wood, which is very hard and dense. This type of bone has less blood supply than all of the rest of the types of bone. The blood supply is required for the bone to harden or calcify the bone next to the implant. Therefore, it takes approximately 5 months for this type to integrate with an implant as opposed to 4 months for type II bone. This type of bone usually takes 4 months to integrate with an implant.
