Structural Evaluation of the Effect of Bone Quality on the Mechanical Interaction between Dental Implants and Bone

Table 1

Time intervals between tooth extraction and implant placement [10].

Group	Method	Advantage	Disadvantage
1	Implant placement right after tooth extraction in the same session	Reducing the overall steps and time of treatment. Maximum bone volume availability and reduced risk of bone resorption. Shortening of the edentulous period. More rapid bone integrity at the site of tissue repair	The socket shape of the teeth may interfere with implant placement in the ideal position. The thickness of the gums makes it difficult to achieve the desired results. Lack of adequate keratinized mucus makes flap adaptation difficult. It requires sufficient experience and needs a bone graft to remove possible bone damage
2	Implant placement after complete soft tissue restoration on the dental sac 4-8 weeks after tooth extraction	Increasing the volume and width of the soft tissue, in order to control the flap. Removal, pathological lesions (4-8 weeks after tooth socket extraction)	Changes from hard tissue analysis may jeopardize implant placement in the ideal position. The treatment time is long. The socket walls of the tooth undergo different analyses. There is a need to increase bone volume
3	Implant placement after complete soft tissue restoration on the dental sac 4-8 weeks after tooth extraction	Relatively easier in socket tooth filling. Easier control, flap with soft tissue maturation	Longer treatment time bone resorption has occurred in some of the socket walls. There is a need for inadequate bone reconstruction
4	Implant placement after complete restoration (after 16 weeks of tooth extraction)	We are facing a restored ridge. The soft tissue has matured	The treatment time is very long. There is a need to rebuild lost bone. The amount of bone available is highly variable and unpredictable
