Review highlights risk of chronic pain after implant surgery

Dental implants have enjoyed a high success rate for many years, but hidden among the success stories are rare cases of a dire side effect: chronic pain. In a retrospective case series published in 2015, a team of researchers with King’s College London analysed several cases involving chronic pain and highlighted the complication to other clinicians. This study was the first to include multiple cases of the rare condition, which had previously only been reported on a case-by-case basis.

Study pinpoints gene which may impact caries development

In a 2015 study, a researcher from Rutgers University, NJ, USA, analysed the salivary protein lactoferrin, finding that a specific gene mutation may impact the development of dental plaque. Lactoferrin is one of several proteins present in all mucosal substances throughout the body and its presence is elevated during infections or inflammation. The author of the study, D.H. Fine, reviewed the protein’s role in various studies and discovered unexpected links between lactoferrin, dental plaque, periodontitis and caries.

Review finds hyaluronic acid may improve wound healing

Researchers from Spain and Italy have published a literature review of dental studies which used hyaluronic acid (HA), suggesting that the chemical may be beneficial in many dental procedures. The authors set out to evaluate HA’s ability to assist healing following several common treatments, as well as evaluating its effect on chronic inflammatory disease.

New 3D-printable scaffold material leverages natural bone’s properties

Researchers at the Johns Hopkins University School of Medicine, Baltimore, USA, have developed a formula for 3D-printable bone scaffolds which may function better than synthetic compounds. The material was developed after the scientists tried to identify how much of a scaffold’s composition could be made of natural, pulverised bone, rather than synthetic materials which are difficult to manufacture.

Study shows implant re-placement in failed sites is viable

A recent study by scientists from China has found that placing new implants in previously failed implant sites is a relatively safe option following early or late implant failure. The research comes at a time when implant failure risk is low, but a deeper understanding of specific risk factors is still required. The authors aimed to evaluate whether implant re-placement in previously failed sites impacted success rates and also to examine bone quality/quantity in these failed sites.

‘Biopen’ allows surgeons to 3D print in the mouth

A team of scientists from Australia has developed a new tool which enables surgeons to ‘print’ biomaterials in clinical situations accurately and effectively. In the case of implant surgery, the new ‘biopen’ could allow clinicians to ‘draw’ cell scaffolds or growth factor shapes in the patient’s mouth using a hand-drawn approach.
