A 54-year-old adult male patient was treated in a private dental office in Padova (Italy) in January 2011.
The patient was healthy, nonsmoking and with good oral hygiene.
Between them, animal Type 1 collagen showed promising results when used as a coating material for etched titanium surfaces [10, 11].
Type I collagen constitutes the largest organic portion of the bone, and in regeneration processes, osteoblastic cells initially deposit a collagen matrix which is subsequently mineralized.
Introduction: The aim of the present study is to describe a case report of lower molars substitution with 2 different dental implants.
Implants Research Paper
One with a DAE surface and one with a type 1 collagen coated surface.The 3 months follow up radiographs showed that bone around the DAE surface dental implant underwent slight preimplant crestal bone resorption since mesially, the head of the implant was no longer covered by bone and distally, the first spire of the implant was no longer covered by bone (Figure 2a).At the same follow up, radiographs of the collagen coated implant showed that bone quantity around the implant surface increased until covering the head of the implant (Figure 2b).The implant supported prosthesis were still in good conditions and there was no need to replace them (Figure 5a, 5b and 5c).Nowadays, dental implants represent the most diffused therapy for substitution of missing teeth.The present case report describes a 6-year follow-up comparison between two titanium dental implants positioned in the same patient; 1 implant had a “DAE” surface and 1 implant had a “DAE” surface and was Type I collagen coated.Figure 2: 3 months follow up radiographs: slight periimplant crestal bone resorption around the DAE surface dental implant (Figure 2a), bone quantity increases around the collagen coated implant until covering the head of the implant (Figure 2b).Indeed, the need for enhanced dental implant survival at sites of lower bone density has stimulated researchers to study new implant surface designs and modifications with the purpose to make molecules that play an important role in bone formation, available exactly where they are needed, that is, the bone-implant interface.These new surfaces are created by both physical and biochemical modifications, coating titanium with biologically active molecules such as peptides, ECM proteins or growth factors [8-9].Even if they are considered a safe and very predictable procedure, the literature still shows many cases of marginal bone loss around implants .In the review of Al-Thobity AM et al., the authors analyzed 23 scientific articles reporting crestal bone loss around implants ranging from .05 mm to .9 mm after 12 to 96 months of follow up .
