Review
A treatment option for managing furcation invasions is root amputation. Long-term survival of resected molars requires a complete harmony of sequential endodontic, periodontic, restorative and maintenance procedures. The main objective of this article is to provide a concise historical perspective of this procedure and to review available literature regarding its efficacy and limitations. It also illustrates a current modification of the procedure using guided bone regeneration (GBR) and socket preservation to eliminate some of the potential disadvantages of the traditional root amputation procedure.

Review
STATEMENT OF PROBLEM
With the increased number of published systematic reviews and in view of their wide clinical applicability, these studies must be carefully assessed before professionals begin to use their recommendations in daily practice, and above all, the methodological quality of this study design must be considered. In implant dentistry, one topic that has been arousing particular interest is the immediate placement of dental implants into infected sites.
PURPOSE
The purpose of this systematic review was to determine the methodological quality of systematic reviews that evaluated the immediate placement of dental implants into infected sites.
MATERIAL AND METHODS
A systematic search was performed by 2 independent reviewers of PubMed, LILACS, and ISI Web of Knowledge up to March 2016. All selected articles were published in the English language. Systematic reviews of original papers that assessed the immediate placement of dental implants into infected sites were eligible for the overview. Narrative reviews, randomized clinical trials, and case reports were excluded. Methodological quality assessment was performed using A Measurement Tool to Assess Systematic Reviews.
RESULTS
Of the 5 selected systematic reviews, 3 were low methodological quality and 2 were assessed as moderate. None were high methodological quality. The first systematic review of the topic was published in 2010, and the most recent, published in 2015, was the only one that performed meta-analysis.
CONCLUSIONS
The systematic reviews that assessed the immediate placement of dental implants into infected sites were assessed as low or moderate methodological quality. The topic focus remains controversial because the implant survival rate, the main outcome considered for the implant placement prognosis, presents contradictory results.

Minimizing alveolar ridge atrophy after tooth removal is crucial for the preservation of the alveolar ridge dimensions for future implant placement and subsequent prosthetic rehabilitation. Methods such as bone grafting have been used extensively but generally focus mainly on maintenance of bone volume and less so on bone quality. To achieve enhanced bone quality, it is important that residual bone graft material particles get replaced by new vital bone. This article describes the rationale for and a technique demonstrating implant site preservation with absorbable bone scaffolding to not only maintain alveolar bone anatomy but also improve bone quality for the long-term stability and success of implant therapy.

Meta-Analysis Review
AIM
This systematic review was aimed at analysing bone dimensional alterations within the first year following immediate implant placement.
MATERIALS AND METHODS
The electronic search was conducted using MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL) and EMBASE from January 1980 to October 2013. Quality assessment of selected articles was performed using Cochrane Collaboration's tool or Newcastle-Ottawa scale according to the design of each study. A meta-analysis was performed to estimate bone dimensional reduction. Weighted mean differences in bone dimension between baseline and follow-up measurement were calculated. Subgroup analysis and mete-regression were conducted to evaluate the effects of different variables.
RESULTS
A total of 1348 articles were identified following the search process. Six studies were included in the present review. The weighted mean buccal horizontal bone dimensional reduction (BHDr) was 1.07 mm and buccal vertical bone dimensional reduction (BVDr) was 0.78 mm. The weighted mean palatal bone dimensional reduction was 0.62 mm horizontally (PHDr) and 0.50 mm vertically (PVDr). The initial thickness of the buccal alveolar plate (TB) of the socket was the only variable significantly correlated with BHDr and BVDr in meta-regression analysis.
CONCLUSIONS
The bone dimensions of immediate implant sites demonstrated approximately 0.5-1.0 mm reduction in vertical and horizontal aspects 4-12 months following surgery. The results should be interpreted with care because of the data heterogeneity. The correlation of the socket buccal wall thickness, and other variables, with dimensional changes of the bony ridge should be investigated further in controlled clinical trials.

Clinical Implant Dentistry and Related... Apr 2017The aim of the present study was to assess bone volume changes in maxillary molar regions after delayed implants placement.
BACKGROUND
The aim of the present study was to assess bone volume changes in maxillary molar regions after delayed implants placement.
MATERIALS AND METHODS
Patients presented large bone defects after tooth extractions. Reactive soft tissue was left into the defects. No grafts were used. Cone beam computed tomography (CBCT) scans were performed before tooth extractions, at implant placement (at 3 months from extraction) and 3 years after implant placement, bone volume measurements were assessed.
RESULTS
Bucco-lingual width showed a statistically significant decrease (p = .013) at implant placement, 3 months after extraction. Moreover, a statistically significant increase (p < .01) was measured 3 years after implant placement. No statistically significant differences (p > .05) were found between baseline values (before extraction) and at 3 years from implant placement. Vertical dimension showed no statistically significant differences (p > .05) at implant placement, 3 months after extraction. Statistically significant differences (p < .0001) were found between baseline values (before extraction) and at 3 months from implant placement as well as between implant placement values and 3 years later.
CONCLUSION
CT scans presented successful outcome of delayed implants placed in large bone defects at 3-year follow-up.

BACKGROUND
The rate of reparative osteogenesis controls when an implant is sufficiently stable as to allow functional loading. Using a mini pig model, the rate of reparative osteogenesis in two types of implant sites for example, an osteotomy versus a fresh extraction socket were compared.
METHODS
Eight adult mini pigs were used for the study. In phase I, three premolars were extracted on one side of the oral cavity; 12 weeks later, in phase II, osteotomies were produced in healed extraction sites, and contralateral premolars were extracted. Animals were sacrificed 1, 5, and 12 weeks after phase II. Bone repair and remodeling were evaluated using quantitative micro-computed tomographic imaging, histology, and histochemical assays coupled with quantitative dynamic histomorphometry.
RESULTS
One week after surgery, extraction sockets and osteotomy sites exhibited similar patterns of new bone deposition. Five weeks after surgery, mineral apposition rates (MARs) were elevated at the injury sites relative to intact bone. Twelve weeks after surgery, the density of new bone in both injury sites was equivalent to intact bone but quantitative dynamic histomorphometry and cellular activity assays demonstrated bone remodeling was still underway.
CONCLUSIONS
The mechanisms and rates of reparative osteogenesis were equivalent between fresh extraction sockets and osteotomies. The volume of new bone required to fill a socket, however, was significantly greater than the volume required to fill an osteotomy. These data provide a framework for estimating the rate of reparative osteogenesis and the time to loading of implants placed in healed sites versus fresh extraction sockets.

Review
Implant placement in fresh extraction sockets in conjunction with appropriate guided bone regeneration is well documented. The decision to extract teeth and replace them with immediate implants is determined by many factors, which ultimately affect the total treatment plan. The goal of this article is to review some of the important clinical considerations when selecting patients for immediate implant placement, and to discuss the advantages and disadvantages of this mode of therapy.

BACKGROUNDS
This paper describes an additional benefit in double anterior segmental osteotomy to correct severe anterior protrusion in adult patients with extremely thin mandibular alveolus and ankylosed tooth. For the optimal anterior segmental retraction, an ankylosed posterior tooth needed surgical inclination reposition. During anterior segmental osteotomy surgery under local anesthesia, additional single tooth osteotomy was performed without challenge.
METHODS
For anterior segment retraction, osteotomy cuts were made by the surgeon to define a block of bone embedding 6 mandibular anterior teeth. First premolars were extracted during initial orthodontic treatment period. But the ankylosed lower left lateral incisor and lower right second premolar root which remains mesially with uprighted crown hindered further anterior segment retraction. The authors removed cortical bone around second premolar root and repositioned to be upright. Anterior segment was retracted to proper position utilizing the space gained.
RESULT
Thin alveolar mandibular anterior segment retraction and the second premolar uprighting were managed effectively with additional single tooth segmental osteotomy during anterior segmental osteotomy.
CONCLUSION
Double anterior segmental osteotomy can be an effective alternative to conventional orthognathic surgery in selected adult patients.
