Which type of attachment system is most effective for connecting implants to dentures?

For adults with complete tooth loss, the modern approach is to use implant dentures with attachment systems, these connect the implant to the undersurface of the dentures. The choice of the number of implants and the design of the attachments influences the success of the dentures, the amount of wear and tear, patient satisfaction, preference and cost.

Professional oral mouth care for nursing home residents: is it more effective than usual care?

Pneumonia is common among elderly people living in nursing homes. Nursing home‐acquired pneumonia (NHAP) is a bacterial infection of the lung that occurs in residents of long‐term care facilities and nursing homes. Poor oral hygiene is considered to contribute to the likelihood of contracting an infection. Professional mouth care is a combination of brushing teeth and mucosa, cleaning dentures, using mouthrinse, and check‐up visits to a dentist, while usual mouth care is generally less intensive, and is self‐administered, or provided by nursing home staff without special training in oral hygiene.

More research is needed on the best techniques and materials for making dentures

It is common for elderly people to have lost some, or all of their teeth (edentulism). This has a significant impact on their quality of life. There are several steps to making complete and removable partial dentures. The final impression is a very important step for ensuring the quality of the denture in terms of satisfaction, comfort, stability of the denture, and chewing ability. There are a number of different techniques and materials used for making the final impression for complete dentures or removable partial dentures. There is no consensus on which are the best.

Comparing dental implants – does material, surface coating or shape make a difference?

Dental implants

Missing teeth can sometimes be replaced with crowns, bridges or dentures, which may be attached to dental implants. Many different types of implant exist; more than 1,300 are available in different materials, shapes, sizes and with different surface characteristics or coatings. This newly updated review on the Cochrane Library compares the different types of implant, in terms of how often they fail and have to be removed. Failure could be biological and caused by bone loss or infection; or mechanical, where the implant itself fractures. Continue reading

New titles registered at the Cochrane Oral Health Group

After the Cochrane Oral Health Group Editorial Meeting, a total of EIGHT new titles were registered. It has been a bumper month!

Approximal sealing for managing dental decay in primary and permanent dentition
by Mojtaba Dorri, Wael Sabbah, Bahar Kiani

This new review is from a team based in London, Portland (USA) and Mashhad (Iran). It will assess  the effectiveness of different methods and materials used for sealing approximal surfaces in order to manage dental decay.

Dental cavity liners for Class I and Class II resin-based composite restorations
by Andrew B. Schenkel, Ivy Peltz and Analia Veitz-Keenan

This team, based at New York University, will look at whether there is any benefit in placing dental cavity liners in resin-based composite restorations, considering any type of liner (to include calcium hydroxide, glass ionomer, flowable composite, zinc phosphate cement and zinc eugenol cement).

Maxillary distraction osteogenesis versus orthognathic surgery in cleft lip and palate patients
by Dmitrios Kloukos, Piotr Fudalej, Patrick Sequeira and Christos Katsaros

There are two widely used types of surgical reconstruction for cleft lip and palate patients: maxillary distraction osteogenesis and orthognathic surgery. This review will compare the two. The team is based at the University of Bern in Switzerland, and in Nijmegen, Netherlands.

Prevention and treatment of oral candidiasis in edentulous patients
by Analia Veitz-Keenan, Silvia Spivakovsky, Leila Jahangiri, Winnie Furnari

Is any one treatment better than another in preventing and treating oral candidiasis in edentulous patients? This review, from a team based at New York University, will look at this question.

We look forward to receiving the protocols of these new systematic reviews.

In addition to these four titles, another four have been registered as part of a grant from the Centers of Disease Control and Prevention. Led by Dr. Anne-Marie Glenny, the project to update five systematic reviews is now underway. Joining Anne-Marie on the review team will be Ashwini Sreekanta, Dr. Tanya Walsh and Professor Helen Worthington. They will be working on:

  • School-based and school-linked fissure sealant delivery programs for the prevention of dental caries
  • Community wide fissure sealant promotion programs
  • Water fluoridation for the prevention of dental caries
  • Population based interventions for the prevention of sports-related craniofacial injuries

New title registered at the Cochrane Oral Health Group

The Cochrane Oral Health Group has registered a new title:

Optimal treatment for the edentulous mandible

The review will be led by Leila Jahangiri from New York University. Also on the team are Mijin Choi, Marjan Moghadam, Michael Ferguson and Ivy Peltz, also from New York University. We look forward to publishing the protocol from this new review team at some point in the next year.
