We had long discussions about implants can be problematic if you take impacts while having an implant in your face but we never talked about how weak your jaw will be after osteotomies.
Osteotomies are not superior to implants when it comes to impact effects on facial bones.
1-Weaken Jaw Due To Lengthen It
Look at these pictures for example. You will have longer, wider mandible with weak cut points. Those bones will attached due to healing with a thinner layer.
So if you take an impact from those points, it will more likely to have fractures, and we know jaws are easy to be fractured with strong impacts.
2-Implants Vs. Mandibular Osteotomies
However, we know that jaw implants create bony layer over implants through the years. So basically your jaw will be stronger than ever.
Here is bony layer parts pointed especially on the angle part :
Only disadvantage that jaw implant can create that the bone resorption.
3-Studies About Bone Resoprtion
This study showed that, jaw angle implants has only 2 mm (at max) bone resorption, which is called implant settlement up to 20 years.

The normal bone resorption for people having age without implants is 0.05–0.13 mm annually. Because as we get older, our facial bones are getting smaller too due to enviromental changes and genetic process. Here is the study below :

Following studies show bone resorption levels on chin, jaw implants. No bone erosion, only bone resorpiton

CONCLUSION :
Implants create resorption on facial bones for sure but the only study we have shows that resorption don't exceed 2mm at worst.
However, we need furthermore, long studies to discuss if implants erode the bone itself through the years.

"Facial Skeletal Reconstruction Using Porous Polyethylene Implants"
A retrospective review of clinical outcomes was performed to determine the clinical utility and morbidity associated with the use of porous polyethylene facial implants. Three hundred seventy implants were placed in 162 consecutive patients, in 178 operations performed in 11 years.
The normal bone resorption for people having age without implants is 0.05–0.13 mm annually. Because as we get older, our facial bones are getting smaller too due to enviromental changes and genetic process. Here is the study below :
