Effect Of Low-Level Diode Laser Bio-Stimulation On Implant Stability Before, During And After Immediate Implants In Mandibular Molars. (A Randomized Clinical Study), Ahmed Elsayed Fahim A.Faim, Ahmed Farid Shehab, Waleed Ragab El-Beialy, Ahmed Abozekry

Future Dental Journal

Introduction: Tooth loss can affect the person’s life dramatically. Tooth loss is accompanied by bone loss in all dimensions, so preservation of the bone is mandatory for placement of dental implant.

Immediate implant can preserve alveolar bone. Due to difference in shape between the implants and extracted roots a gap appears between the immediately placed implant and the extraction socket resulting in jumping distance, Bone grafts are commonly used to fill this gap, recent studies suggest that jumping gaps shouldn’t always be grafted.

Low level bio stimulation has stimulatory effect on bone cells so it can be used in immediate …

Combatting Bacterial Infections: The Efficacy Of Poly-Gamma-Glutamic Acid On The Prevention Of Nasopharyngeal Infections Among Individuals With Cleft Lip And Palate, Florence Pun

Scripps Senior Theses

Cleft lip and palate (CLP) is a medical condition where children are born with an unfused lip and palate. While surgery is required to fuse the lip and palate, there are other conditions that children with CLP face after surgeries, such as otitis media (OM), speech impediments, and difficulty breathing. Particularly, OM occurs frequently in individuals with CLP because the tensor veli palatini muscles cannot open the Eustachian tube frequently and ventilate the middle ear properly, even after surgery. This thesis is a research proposal to evaluate whether γ-PGA can be used in nasal washes to safely prevent nasopharyngeal infections …

Comparing Medium To Long-Term Esthetic, Clinical And Patient-Reported Outcomes Between Freehand And Computer-Assisted Dental Implant Placement, Sun Heng

Chulalongkorn University Theses and Dissertations (Chula ETD)

Objective: The aim of the study was to compare medium to long-term clinical and patient reported outcomes between implants placed with Computer-assisted Implant Surgery (CAIS) and freehand protocols. Materials and Methods: Thirty dental implants in the anterior maxillary region with an average of 4 years after loading were assessed by means of Pink Esthetic Scores (PES), Marginal Bone Level (MBL), clinical and patient reported outcomes. Results: CAIS significantly outperformed freehand placement with regards to PES scores (p=0.011). Likewise, implants placed with CAIS showed significantly higher marginal bone levels (p<0.001). Bleeding on Probing, Probing depth and prevalence of mucositis did not differ between the groups, while no peri-implantitis was diagnosed. Conclusions: The use of CAIS lead to superior outcomes in terms of esthetics and marginal bone levels for implants placed in the aesthetic zone as observed in medium to long-term follow-up. No difference was however observed with regards to peri-implant mucosa inflammation.
