JAWBONE
CANCER DETECTED
Although rare, cancer of the jawbone may manifest or
first be noted as a toothache or hypermobility of isolated teeth.
Dr.
Newhart
recently helped diagnose a lymphoma with a
Charleston
oral surgeon. The case was
originally thought to be endodontic in nature.
However, additional radiographs showed multiple
teeth with widened ligaments and a “starburst” appearance
in bone.
Dr.
Newhart
feels that sometimes a co-diagnosis is
beneficial for cases that are not obvious.
THREE-WAY
TUNNELING
Nevins et al. (IJPRD2009; 29: 371-383) attempted a minimally
invasive tunneling procedure using three different types of bone
grafting materials, along with recombinant human platelet-derived
growth factor. Twelve
patients were divided into three groups with one group
receiving freeze-dried bone allograft, another
receiving anorganic bovine bone graft/mineralized, and the third group
receiving a collagen bone substitute.
Re-entry and implants were attempted at approximately fourteen
weeks. New bone formation
was consistently found and implants were able to be placed in the
first two groups with bone grafting.
The collagen bone substitute had disappointing results.
The authors found that within their study, free-dried bone
allograft and anorganic bovine bone graft were appropriate scaffolds
for tunneling procedures and to deliver the recombinant
platelet-derived growth factor.
Dr. Newhart
also performs this tunneling procedure in the posterior arches, as it is
less painful and sometimes less costly than doing standard block
grafting. However, he also
uses a barrier membrane to help hold the graft in place.
27-YEAR
GUARANTEE
Agudio et al. (JPerio2009:80;1399-1405) performed a
10-27 year long retrospective split-mouth study for 55 subjects with
73 areas which had undergone Free Gingival Grafts.
The treated site was compared with the non-treated site over
the period when the patient first presented for treatment until the
final examination. Agudio
found over the follow-up that gingival recession was reduced in the
treated sites. Whereas, in
untreated areas, gingival recession had continued to increase.
The authors concluded that gingival grafted areas showed a
tendency for stability or for increasing the amount of gingiva,
whereas untreated areas showed a tendency for further gingival
recession over time.
Dr.
Newhart
feels that whenever an area has early gingival
recession with very thin gingiva, many times it is better to graft
these areas as we know this will be a successful procedure for the
lifetime of the patient.
REPLACING
THE LATERALS
Degidi et al.
(Jperiol:80;1393-1398) performed a 3-year randomized clinical trial on
immediate versus one-stage restoration of 3.0mm Xive dental implants.
Sixty patients either had a 3.0mm Xive implant placed with a
temporary crown, or placed with a surgical cover screw and uncovered
in six months. The authors
looked a final probing depth and boneloss after the finalcrowns were placed on these teeth.
The results showed 100% implant survival for the sixty implants
placed. Mean pocket depth
was .85mm and bone loss was approximately 2mm from the original
implant placement. There was no statistical significance between
placing a temporary crown at the time of implant surgery or doing a
two-stage technique. The
authors conclude that there is no difference between one and two-stage
treatment, in that a 3.0mm Xive implant prove to be a very predictable
treatment option for replacement of lateral incisors.
Dr. Newhart
does place 3.0mm Xive implants in lateral incisor sites and has had
extremely good results when placed according to their treatment
protocol.
