laser fabrication (DLF) is a new technology by which we can produce a dental implant with complex geometry that allows better osseointegration,
through enhancing the differentiation of stem cells into osteoblasts and endotheliocytes leading to bone formation around the implant in a better and
quicker way.
Objectives: to compare osseointegration between laser sintered implants and acid etched implants.
Materials and methods: This randomized clinical trial was conducted on twenty patients having edentulous spaces in the maxillary premolar area.
They were divided equally into two groups, group A and group B, ten patients in each group. Laser sintered implants were placed in the edentulous
spaces in group A patients, while conventional implants were placed in group B patients. Clinical and radiographic evaluations were carried out
after 4, 6 and 9 months for both groups.
Results: : Regarding the plaque index the scores of group A were found to be insignificantly lower than those of group B at 4 and 6 months and
significantly lower at 9 months. The mean probing depth values in group A were significantly lower than group B at 4 and 6 months and
insignificantly lower at 9 months. While, the implant mobility score was 0 for both groups. Regarding the mean marginal bone defect, values for
group A were insignificantly lower than group B at 4 months, while significantly lower at 6 and 9 months.
Conclusion: The use of both laser sintered and acid etched implants for replacement of maxillary premolars have significant success
