Posttraumatic Use of Dental Implants Immediately After Tooth Extraction: Clinical Study

Treatment options for permanent teeth with coronal one-third root fractures

BACKGROUND AND OVERVIEW

Teeth with coronal one-third root fractures are considered to have a poor prognosis. Historically, such teeth were likely to be extracted. Observations have indicated that at least some teeth with such fractures can survive for a significant amount of time.

CASE DESCRIPTIONS

The authors report on 2 cases of coronal one-third root fractures that have survived for 10 and 35 years and suggest that the long-term splinting of these teeth aided in their survival.

CONCLUSION AND PRACTICAL IMPLICATION

Stabilizing teeth with coronal one-third root fractures may allow such teeth to survive for long periods, which can be of great benefit, especially for young patients.

Immediate Implants: Clinical Guidelines for Esthetic Outcomes

Research has shown that tooth loss results in morphological changes in alveolar ridge that may influence the subsequent implant placement. Immediate implant placement was introduced as a possible means to limit bone resorption and reduce the number of surgical procedures following tooth extraction. Histological and clinical evidence from human clinical studies showing efficacy of immediate implants has come to light over the last decade or so. However, immediate implant placement is a challenging surgical procedure and requires proper case selection and surgical technique. Furthermore, there appears to be a lack of clinical guidelines for immediate implant placement case selection. Therefore, the aim of this mini-review is to analyze critical evidence from human studies in order to establish clinical guidelines which may help clinicians in case selection when considering immediate implant placement protocol.

Clinical Outcomes of Implants Placed in Extraction Sockets and Immediately Restored: A 7-Year Single-Cohort Prospective Study

BACKGROUND

The placement of implants immediately after tooth extraction has proven to be a predictable treatment strategy with a very high success rate.

PURPOSE

The aim of the present 7-year prospective single cohort study was to evaluate the success rate, marginal bone level (MBL), soft tissue stability of implants placed in fresh extraction sockets and immediately restored.

MATERIAL AND METHODS

This prospective cohort study included 37 implants in 32 patients (19 females and 13 males) with an average age of 40.1 ± 13.3 (range: 21-63 years) who received immediate implants and immediate single unit restorations. Outcome evaluations were: implant failures, complications, MBL, width of keratinized gingiva, facial soft tissue (FST) levels, modified Plaque Index and modified Bleeding Index.

RESULTS AND CONCLUSIONS

The cumulative survival rate was of 94.6% at 7-year visit. The mean MBL was -0.6 ± 0.49 mm at baseline and 1 ± 0.2 mm after 7 years. The FST Level was 0.4 ± 0.69 mm at baseline and 0.02 ± 0.70 mm at the 7-year follow-up. The Width of Keratinazed Gingiva was 3.8 ± 0.47 mm at baseline and 3.1 ± 0.42 mm at 7-year follow-up. Implants placed immediately after tooth extraction and immediately restored showed predictable clinical outcomes in this prospective study.
