I do not think that osteoporosis will have much influence on whether or not you have veneers or porcelain crowns. There are significant advantages of veneers over crowns, number one being that less drilling of the tooth and that the underlying tooth will be stronger. In my own mouth I would want veneers over crowns any time that I would have the option.Recession is not generally caused by veneers or crowns. More often a function of age, biting or grinding the teeth, clenching the teeth, thin gums, prominent roots, previous history of orthodontics, etc. Properly done, it is my opinion that veneers or crowns will have much influence on whether your get gum recession.Does recession change the look of the mouth? Yes, in respect that if you have a high lip line (meaning when you smile you show all of your upper front teeth and some gums) that recession will make your teeth look longer. Longer teeth with less gums is an "older look", but again you may not have much control over that. In some cases if you get significant recession you may be able to have a periodontist (gum specialist) graft gum tissue back onto the teeth and roots. This is a common procedure that most gums specialists do routinely.
