Abstract
Bone Density and Maturation after Tooth Extraction in the Upper Maxillary Molar Area and a New Technique of an Immediately Loaded Implant in Soft Bone: A Case Report
Highlights
A significant loss of tissue contour occurs during the first month after tooth extraction, which may range from 3-5 mm in width after 6 months [1,2]
This case report is divided into 2 parts, the first part demonstrates the increases in bone density over time after tooth extraction, and significant differences were observed in the stability of the primary implants
Progressive implant loading was invented by Misch12 and is recommended for implants that are placed in soft bone or grafted sites
Summary
A significant loss of tissue contour occurs during the first month after tooth extraction, which may range from 3-5 mm in width after 6 months [1,2]. Special care should be taken when implants are placed in the posterior maxillary area, such as undersized bone preparation to obtain primary stability, implant surface modifications (roughened surface), implants with a wide diameter, an aggressive implant design, the submerged technique and a long healing period. The extraction was performed in a non-traumatic procedure, and the patient was advised to wait 8 weeks for the tooth to completely heal before implant placement. The right implant was immediately loaded using a temporary plastic abutment, and the crown was fabricated from light-cured composite material (Figure 3) At this stage, the crown was out of occlusion with a narrow occlusal table and no adjacent contact (Figure 4).
