Background:
Some studies have indicated that marginal bone loss at implants and at teeth are similar, while results from other studies showed that implants lost more bone than teeth in the same dentition.
Aim:
To determine the amount of progressive marginal bone loss that had occurred at implants and teeth in the same segment of the dentition following implant placement in partially dentate subjects.
Material And Methods:
A total of 217 patients with a total of 573 implants and 318 teeth present in the same segments of the dentition were included. Radiographs were available from 1 year (baseline) and ≥3 years after loading.
Results:
The mean bone loss that occurred between the two examinations was at implants 0.42 ± 0.68 mm and at teeth 0.44 ± 0.52 mm. Thirty-eight subjects (18%) had ≥1 implant exhibiting >1 mm bone loss. Bone loss at the 148 implants in this category of patients was 1.30 ± 1.04 mm with a corresponding loss at the 69 teeth of 0.53 ± 0.62 mm. Eighteen subjects (8%) had ≥1 tooth that exhibited >1 mm bone loss. The mean amount of bone loss in this sample was 1.37 ± 0.87 mm (38 teeth) and 0.29 ± 0.31 mm (56 implants).
Conclusions:
This study showed that marginal bone loss at implants and teeth in many partially dentate subjects might be independent phenomena.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
