Tratamiento con plasma rico en plaquetas podría ayudar a la formación de hueso luego de una extracción
El Journal of Oral Implantology publicó recientemente que el uso de plasma rico en plaquetas, posterior a una extracción dental, puede acelerar el proceso de curación y acelerar la formación de hueso.
La afirmación parte de un estudio en el cual se practicaron extracciones de lado y lado a cierto número de pacientes. En el lado derecho se usó un tratamiento con el Plasma Rico en Plaquetas (PRP) y se observó una significativa mejor recuperación y un mejor proceso de sanación. El estudio incluyó exámenes con radiografías practicados sobre los pacientes en las semanas 1, 2, 3, 4, 6, 8, 12, 16, 20 y 24.

When a tooth is removed, poor healing can lead to excessive bone loss in the jaw that can delay tooth replacement, require costly reconstructive surgery, or even be impossible to fix, according to the authors. “Patients and clinicians could benefit if a cost-effective, simple technique were available that decreased bone-healing time and increased the predictability of favorable results,” they write.
For the study, radiography techniques were used with patients to detect bone changes after surgery to remove molars – specifically, the bilateral mandibular third molar. For each patient, one extraction site was treated with PRP and the site on the other side of the mouth was not, serving as the control. Three patients received PRP on the right side and three on the left.
The patients returned after the operation for evaluations and digital radiographs at 3 days plus weeks 1, 2, 3, 4, 6, 8, 12, 16, 20, and 24. Observers checked them visually to evaluate the extraction site’s tissue opening, bleeding, inflammation, facial edema, and pain. The early radiographs found a significant increase in bone density in the PRP-treated sites.
“The PRP treatment had a positive effect on bone density immediately following tooth extraction,” the authors write, while the control site had a decrease in bone density during the first week after surgery. After the initial two weeks, both sites had relatively parallel increases in bone density.
“It took approximately 6 weeks for the control sites to reach the same bone density that the PRP-treated site had reached by week 1,” according to the article. “The immediate start of bone formation seen with PRP treatment is of clinical relevance because it is the initial 2 weeks following bone-manipulation oral surgery that are important.”
Patients did not report significant differences in their perception of pain, bleeding, numbness, facial edema, or temperature between the different sites, according to the study.
Faster bone formation could benefit patients who need immediate prostheses or dental implants, according to the article’s authors, because the current 4 to 6 month wait for these could be reduced to 2 to 4 months if PRP is used.
Some studies report that PRP does not affect bone formation yet others, such as this study, do report faster bone formation. Rutkowski et al. hypothesize that it is how the PRP is prepared and what time points are used for measurement that influence bone formation results.
Overall, the authors conclude that PRP increases the rate of bone formation and decreases the healing time during the initial 2 weeks after surgery, helping patients return to “full function” sooner.
