[PDF] Clinical and esthetic outcomes of implants placed in postextraction sites. | Semantic Scholar (2024)

The available evidence suggests that esthetic outcomes, determined by esthetic indices and positional changes of the peri-implant mucosa, may be achieved for single-tooth implants placed after tooth extraction.

Placement of dental implants at an early timing after tooth extraction may offer advantages in terms of soft and hard tissue preservation, when compared with a delayed protocol.

Limited data on Type 2 and Type 3 implant placement appear to indicate that they can perform well both short and long term, however, the limited number of cases, the significant heterogeneity of the included studies and the high risk of biases importantly reduce the generalizability of the findings.

The current literature indicates that immediate or early placement of single-tooth implants after tooth extraction may be a viable treatment with long-term survival rates and marginal bone level conditions matching those for implants placed conventionally in healed bone ridges.

Because of the low number of included studies and the heterogeneity of study design, more well-designed studies are required to assess the relevance of this treatment alternative.

Both immediate and early implant placement protocols presented stable treatment results in terms of esthetic outcomes at the 1, 2, and 10-years follow-up and Loading protocols did not seem to influence esthetic outcome in short- and medium-term follow-ups.

The topic of this paper is the timing of dental implant placement in the esthetic zone in relation to removal of the tooth to be replaced.

According to the current evidence, short-term esthetic outcomes of peri-implant soft tissue did not show significant difference following type 1 and type 3 implants placement with well-selected patients, however, caution should be taken for clinicians to extrapolate this result to all types of patients.

A systematic review of the literature to compare soft tissue aspects of immediate and delayed implant placement in esthetic areas concluded that both treatment options for implant placement demonstrated similar outcomes in the esthetic area, especially when PL was considered.

Immediate and delayed immediate implants appear to be predictable treatment modalities, with survival rates comparable to implants in healed ridges, and clinical outcomes of immediate and delayed implants were comparable to those of implants placed in healed alveolar ridges.

Questions regarding whether peri-implant health, prosthesis stability, degree of bone loss, and esthetic outcome of immediate or early placed implants are comparable with implants placed in healed sites remain unanswered.

Careful evaluation of potential extraction sites before immediate implant installation promotes optimal implant esthetic results, as shown in the results of this prospective study.

One-stage implant osseointegration in extraction sockets is enhanced if used with this synthetic graft material, and the simplicity of the method does not jeopardize outcome and predictability.

The results of this study suggest that favorable implant success rates, peri-implant tissue responses, and esthetic outcomes can be achieved with immediately placed and provisionalized maxillary anterior single implants.

Immediate implant placements are believed to preserve soft and hard tissue form and contours, reduce the need for augmentation procedures, minimize surgical exposure of the patient, reduce treatment time and improve esthetic outcomes.

The criteria for success were complete stability and no further bone loss than had appeared at the second stage surgery and on the day of restoration, and the overall survival rate in this current study is 95%.

The results indicate that successful bone fill can be achieved with GBR; this is more feasible in the maxilla, when a provisional restoration is used, and early implant placement timings seem to be preferable.

implants placed into fresh extraction sockets with or without regenerative procedures and used to support single crown prosthesis showed a very high cumulative success rate (97%) in a 4-year prospective study.
