Four Modalities of Single Implant Treatment in the Anterior Maxilla: A Clinical, Radiographic, and Aesthetic Evaluation

Abstract

All treatment modalities were predictable from a clinical and radiographic point of view. However, advanced reconstructive surgery, especially BGR, increased the risk for complications and compromised aesthetics. Research is required on the prevention and minimally invasive treatment of buccal bone defects at the time of tooth loss to avoid complex therapy.

Bone volume changes after immediate implant placement with or without flap elevation

“…Similarly, Cosyn et al (2013) observed similar pink esthetic and white esthetic scores in the delayed and immediate implant placement groups.…”

“…In our study we found a vertical resorption of 0.48 ± 1.35mm on the buccal crest, which is in the range of other studies (0.1-1mm). The two retrospective studies with a follow up of 3 (Cosyn et al 2013) and 7 years (Benic et al 2012) show a bone reduction of around 1mm. It can be suggested that, although most dimensional changes occur within the first 6 months of healing, small alterations may still take place after this period.…”

“…The prevalence of advanced recession (>1mm) after immediate implant placement was systematically addressed by Cosyn et al (2013). Slight interproximal recession (<1mm) was reported in 11 out of the 13 selected studies.…”

“…When analyzing the outcomes of both systematic reviews, it has to be considered that Cosyn et al (2013) only included studies in which implants had been placed in intact sockets, whereas Chen & Buser (2009) included all types of sockets.…”

“…As oral soft tissues follow the underlying bone contour, an intact buccal bone wall seems to reduce the risk of midfacial recession (Cosyn et al, 2013;. Therefore an adequate case selection, meaning intact socket walls, is essential to limit the occurrence of esthetic failures.…”
