Abstract

Introduction: conventionally dental implants were produced by machining titanium rods, then surface treatments or coatings are applied. The direct laser fabrication (DLF) is a new technology by which we can produce a dental implant with complex geometry that allow 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 study was conducted on twenty patients having edentulous spaces in the maxillary premolar area. They were divided equally into two groups, group Aand group B, ten patients in each group. A laser sintered implants were placed in this edentulous spaces in group A patients and a conventional implants in group B patients. Clinical and radiographic evaluations were carried out after 4, 6 and 9 months for both groups.

Results: the mean plaque index scores for group A were (0.80 ± 0.11, 0.80 ± 0.11and 0.68 ± 0.12), for group B were (0.90 ± 0.13, 0.85 ± 0.13, 0.80 ± 0.11) at 4, 6 and9 months respectively. The mean probing depth values in group A were (1.78 ± 0.33,2.29 ± 0.33and 2.59 ± 0.32) for group B were (2.51 ± 0.33, 2.71 ± 0.35 and 2.78 ± 0.24) at 4, 6 and9 months respectively. The implant mobility score 0 for both groups. The mean marginal bone defect values for group A were (1.34 ± 0.11, 1.71 ± 0.03 and 1.98 ± 0.05) for group B were (1.35 ± 0.09, 1.82 ± 0.07 and 2.05 ± 0.06) at 4, 6 and 9 months respectively

Conclusion: The use of both laser sintered and acid etched implants for replacement of maxillary premolars have significant success.
