PURPOSE: This clinical study using a specific technique was carried out to

determine the clinical effectiveness of zygomatic implants under an immediate

loading protocol. MATERIALS AND METHODS: All patients treated between May 2000

and October 2006 who received zygomatic implants were included in this

retrospective analysis. All patients were treated using the same surgical and

restorative protocol. The following data were recorded: gender, age, type of

implant, number of implants placed, dimensions of implants, and implant and

prosthesis survival. RESULTS: Fifty-six consecutive patients (29 women, 27 men;

mean age of 60.58 years [range, 38.78 to 84.01]) were treated. All were in need

of oral reconstruction and had maxillary atrophy that warranted zygomatic implant

placement. One hundred ten zygomatic implants were placed in these 56 patients.

Four of the 110 zygomatic implants failed, resulting in a cumulative survival

rate of 96.37% with follow-up data no less than 9 months and in excess of 5

years. All four failures were turned-surface zygomatic implants. There have been

no failures to date with the titanium anodized-surface zygomatic implants. The

prosthesis survival rate was 100.0%. CONCLUSION: In this retrospective analysis



of 56 patients receiving 110 zygomatic implants, the survival rate of zygomatic

implants was in excess of 96% over a period of 9 months to 5 years. This

technique resulted in a stable and predictable prosthetic reconstruction.

Background: Evaluation of the clinical conditions following computer guided

treatment planning and flapless surgery is still limited. Objectives: The

objective was to evaluate the soft tissue conditions and marginal bone changes

after 1 year of function around immediately loaded implants inserted in edentate

jaws following computer guided treatment planning and flapless surgery. Material

and Methods: Twenty-nine edentate jaws (19 maxillae, 10 mandibles) treated with

165 implants using the Teeth-in-an-Hour protocol were included. In these

patients, peri-implant soft tissue conditions and radiographic marginal bone

changes were evaluated after >/=1 year of functional loading (mean: 19 months).

Results: The mean probing depth at case level was 2.6 mm (SD: 0.6). Bleeding on

probing was recorded as a mean of 81.9% (SD: 23.0). Plaque index showed a wide

range of 0-100%. The mean marginal bone change of measured sites evaluated on

intraoral radiographs was -1.2 mm (SD: 1.4). A marginal bone loss more than 1.5

mm or 2.0 mm was observed in 42% and 27% of the measured sites, respectively. A

pressure-like-ulcer was found in 9 cases. Implants with marginal bone loss of

>1.5 mm were more frequently observed in cases with an ulcer than cases where no

ulcer was found. Conclusion: Although the mean marginal bone loss after function



in the present study was within the range of other reports presenting mean bone

loss data after immediate implant loading, our patients showed a wide range of

bone loss with several sites, where the bone loss was greater than the commonly

used successful level (>1.5 mm).

CAD / CAM dental systems in implant dentistry: update.

CAD/CAM systems (computer-aided design / computer aided manufacturing) used for

decades in restorative dentistry have expanded its application to implant

dentistry. This study aimed to look through CAD/CAM systems used in implant

dentistry, especially emphasizing implant abutments and surgical templates

manufacturing. A search of articles published in English at Medline and Scopus

databases at present was conducted, introducing "dental CAD/CAM" , "implants

abutments" and "surgical guide CAD/CAM" as key words. These systems consist of

three components: 1) data capture using optical systems or laser scanning, 2) CAD

for the design of the restoration, and 3) CAM to produce the restoration through

the information generated by computer. CAD/CAM abutments present the advantages

of being specific to each patient and providing a better fit than the rest of

abutments, in addition to being much more tough as they employ materials such as

titanium, alumina and zirconium. In order to improve accuracy during implant

placement we use stereolithography to manufacture CAD/CAM surgical templates.



Using this method, minimally invasive surgery is performed without a flap, and

the prosthesis is delivered, achieving immediate functional loading to the

implants.
