Recent Advances In Implants Every Dentist Ought To Know

How To Manage Papillary Deficiencies Between Implants ?
A number of cases show deficiency of papilla in the interdental area, which may be between implants, or an implant and teeth. This can impose critical esthetic problem for the patient as well as the dentist. The most recent advancement in this field is the injection of hylauronic acid commercially availabel as Restylane (TM). The effect lasts for 6-24 months after which a new dose is required. (1)

Maxillary Sinus Floor Augmentation
Recently Calcium sulfate has been used for maxillary sinus floor augmentation. Calcium sulfate placement showed significant maxillary sinus bone formation. Placement of implants after this procedure led to successful implant placement and loading. (2)

Can Bone Regeneration Occur In Uncontrolled Diabetic Patients ?
Diabetic Patients reporting for implant placement with angular bone loss require bone regenerative techniques before proceeding with implants. Experiments on rats with artificially created bone defects and uncontrolled, drug induced diabetes were carried out. The results were encouraging as it showed significant de novo bone formation via GBR even in uncontrolled diabetics. (3)

Is Osseointegration Possible In Diabetics ?
A review study of MEDLINE/PubMed articles published from 1982 up to and including July 2009 were carried out by researchers. 33 articles were selected. It was concluded that proper glycemic control and HbAA1c in normal range will lead to successful implant osseointegration in diabetics similar to normal individuals. (4)

How Do Implants Fare In Periapically Infected Bone?
Placement of implants in fresh extraction sockets has been taking place for long. How ever a question was intriguing, that whether an immediate implant can survive if placed in an extraction socket of a periapically infected tooth. A 24 months follow up of patients showed 100% success rate in implants placed in the sockets of teeth previously infected at the periapical region. (5)
