“…Bone loss around the implant was one of the factors that caused the failure of dental implants. Many studies have been done on the factors affecting the success of dental implants, but the effects of some factors are still not completely clear [1][2][3][4][5].…”

Objectives One of the most important factors that has influence on dental implants success rate is marginal bone loss. The purpose of this study is to investigate the effect of the implant’s vertical position and the soft tissue’s thickness on the rate of marginal bone loss of the dental implant. Materials and methods In this single-blind randomized clinical trial study, 56 implants placed in the posterior region of mandible of 33 patients (19 women, 14 men) were divided into two groups. The group of crestal (28 implants) and subcrestal (28 implants) implants, each group was divided into two sub-groups with soft tissue thickness of 2 mm and less than 2 mm (14 implants) and more than 2 mm (14 implants). The amount of marginal bone loss was measured by Scanora 5.2 program with radiographs Digital parallelism based on the effect of the vertical position of the implant, soft tissue thickness, three months after placement, and three months after loading implants (six months after implant placement). Results The results showed that marginal bone loss in subcrestal implants is significantly more than crestal implants (p-value = 0.001), and also marginal bone loss in the soft tissue thickness group of 2 mm and less is significantly more than the group of soft tissue thickness more than 2 mm (p-value < 0.001). The amount of marginal bone loss three months after implant loading was significantly higher than three months after implant placement (p-value < 0.001). Conclusion The implant’s vertical position and the soft tissue’s thickness around the implant are effective factors in the amount of marginal bone loss. Marginal bone loss is more in subcrestal implants and in cases with less soft tissue thickness. The time factor significantly affects the amount of marginal bone loss.

Implant restoration, a predictive procedure for edentulous areas, can suffer from early failure due to several factors. While thorough debridement of the extraction socket is standard practice for implant placement, unintentional remnant can occur. This case report presents an early implant failure following placement and guided bone regeneration. Radiological examination revealed radiopaque material around the implant, prompting material removal and subsequent biopsy. The histological analysis identified the area surrounding the bone material as granulation tissue containing chronic inflammatory cells, while the hard tissue area exhibited hypercementosis or periapical cemento-osseoeous dysplasia. These findings suggest unintentional placement of the implant into a remnant following the previous extraction. This case highlights the importance of thorough debridement after tooth extraction. Moreover, pre-implant placement radiological evaluation is necessary to avoid implant failure associated with unintentionally retaining lesion.
