Oral Crest Lengthening for Increasing Removable Denture Retention by Means of CO₂ Laser

Figure 5

The means and standard deviations of vestibular lengths at the end of surgeries, after 2, 6, and 10 weeks post-op were  mm (initial lengths),  mm (after 2 weeks of post-op),  mm (after 6 weeks), and  mm at 10 weeks of post-op. The difference between means of vestibular lengthening in all groups is significantly different except between means of vestibular lengthening after 6 and 10 weeks of post-op. The loss in the initial vestibular deepening continues to increase significantly until 6 weeks post-op and it becomes statically stable.
